Casfuy Dog Nail Grinder Upgraded: Professional 2-Speed Electric Pet Nail Trimmer – Quiet, Painless Paws Grooming & Smoothing for Stress-Free Care of Small, Medium, Large Dogs & Cats

Easy and quick September 1, 2025 Color: B-dark BlueVerified Purchase I have had the Pet Nail Grinder for a year now, and have used it weekly since it arrived. Following the clear and simple directions, it took very little time for my pup to learn to tolerate having her nails trimmed with the nail grinder. The grinder is very quiet and does a very good job. With just a couple of seconds per toe each week (a total of less than 5 minutes!) my dog's nails are always the correct healthy length. I follow up her pedicures with Musher's Secret paw wax for healthy toe nails and paw pads. I highly recommend this Pet NailGrinder. 19 people found this helpful

good product Copper approved August 12, 2025 Color: B-dark BlueVerified Purchase The item is quite good for a rotary tool that is quiet and effective is pretty nice to have. Also has safety guards for different size dogs so you don't over shave or file your dogs nails. However, I don't think my dog is a fan of it just yet. Gonna need to bribe him with more treats before he gets use to it. Pretty comfy in my hand and the grip is a decent thickness that i don't feel like I am getting arthritis. I think my dog will love his nail filing sessions with this item.

Used for guinea pig nails July 21, 2025 Color: A-WhiteVerified Purchase I bought this as a filer to help file down my guinea pig's nails. One of my piggies has black nails and unfortunately I have clipped the quik and caused her to bleed because I can't tell where it is. I decided to look for a filer/grinder that could help with this task. Upon receiving, the instructions are to hook up to the charger. Cable is included, but not the box. Then I let it charge for about 30 minutes just to see how long it would last to file a couple of nails. It only lasted about 30 seconds before it slowed down, so I let it charge longer this time. There is a light indicator that lets you know when it is done charging because it'll stop blinking. It took about 2 hours to fully charge. Then I was able to use it with ease and grind my piggy's nails with no worry of clipping the quik. The battery did not die and was still going even after I finished. It is very fast and not too noisy which is what I wanted. Great battery life after you let it fully charge. I ordered mine in white and the size is just right to hold. It does get a little hot but since I only have guinea pigs, it might get hotter if you're using it on a larger pet. All in all I would recommend this for pet owners. 15 people found this helpful

Buy this August 15, 2025 Color: A-WhiteVerified Purchase This is going to sound like a fake review but I just cannot express enough how much I love this item. This was the best $20 something I have ever spent. My dog used to freak out seeing the traditional clippers, it would take an hour to do her nails halfway decently and once she even snapped at me. She would take one look at the clippers and run for the hills. Now with this grinder she will sniff it and doesn’t seem too panicked by nail trim day. It’s very quiet while running, easy to use, and the battery lasts forever! The trim is so perfect and precise that I can make sure none of her nails touch the floor by the time I’m done. I’ve had a grinder before but it was huge and loud and she hated it. The safe guard allows me some comfort so I don’t have to worry about hurting her.

It works. Nails trimmed. No more fear, anxiety or drama July 23, 2025 Color: B-dark BlueVerified Purchase This little thing grinds my dog’s nails quickly and quietly with very little vibration. What for years has been a terrifying experience for my dog is now just another day. No more trips to a groomer or vet for nail trims. No more fear, anxiety or meds for my dog for nail trims. Charge holds for multiple uses. Easy to hold in your hand and manipulate speed and off switch. This has totally revolutionized nail trimming for us. She even took a nap during one of our sessions. Do be careful and observant when using. If you are used to your animal pulling away and freaking out, the lack of response can mean they do not give you a warning if you are getting near the quick (this can definitely be an issue with animals with black nails). This is an amazing tool! 19 people found this helpful

WARNING** Long-haired owners tie back hair/loose articles before use. DONT USE ON LONG HAIRED PETS. September 23, 2023 Color: A-WhiteVerified Purchase I gave this product three stars. The reason being is because the product does file pets nails relatively less stressfully, as when a dog nail clippers are in use- if done safely and properly. The product does seem to be of relatively good quality/materials.

That being said, my concern lies in the fact that there are virtually zero safety precautions for material or hair entanglement regarding the presence of any automatic shut off when increased resistance is met. Most other products with rotating components (I.e. handheld fans, vacuum cleaners) can detect if a snag is detected at which point the motor stops spinning and shuts off until the device is cleared of snags and restarted.

In this situation, a single strand of my hair came in contact with rotating end of the dog nail grinder, and it started twisting until an entire chunk of my hair became fully entangled, which happened over the course of approximately 1-2 seconds.
The device continued spinning and spinning and I could not get the sliding on/off switch to slide off because the device continue to spin in my hand. The device was very hot, almost smoking, because of the amount of hair entangling, but it did not turn off.

This had me greatly concerned, not just for myself, but for my dog.

Because my dog is a long-haired mixed breed (Bernedoodle, or Poodle and Bernese Mountain Dog mix), her hair could easily become stuck in the twisting mechanism. Especially because she is also a large breed, meaning we cannot use the included plastic nail guard due to the size and shape of her nails. At which point, this would be much a more painful and traumatizing experience than just using a regular nail clipper, and I do not want to traumatize her… or myself.

I feel like if the rotary mechanism senses a snag or a tangle in the rotating bit, it should have a safety feature that automatically shuts it off so that people and/or their pets do not have hair (or other loose articles) incidentally damaged, burned, ripped out, or removed.

The reason I gave 3 stars instead of 1 is because I understand that this issue is partially my fault and in the future, I would tie my hair back fully if I were to use it again. Also it’s not an entirely useless product, but can only be safely used (in my opinion) on smaller, shorter haired breeds.
With that being said, I am glad this happened to me rather than my pet because I was able to easily cut the affected strands of my hair that were burned and frayed off and am physically unharmed, although my hair does look very strange now since this large strand was in the very front. Regardless, I take some responsibility for the incident, however, I don’t want my situation to happen to any long haired pets in the future and hope the company makes some safety adjustments to the product.

One thing that could significantly improve safety would be to include an overall larger grinding bit that also includes a larger plastic safety guard with a bigger opening for large breed dogs, so that their nails can be filed safely with decreased risk for tangling, ripping, tugging, etc.
As mentioned, I was not able to use the provided guard that comes with the product because my dogs nails are simply too wide/thick to keep the guard on. If you have a small pet with thinner nails, the guard would likely better protect you/your pet or reduce the risk of entanglement by probably 90%.

In conclusion, I will likely not use this on my long haired dogs, but I would be willing to try the product again on my short haired, smaller dog (Boston terrier) because the risk for entanglement is minimal to none (for the pet), and I can use the file guard that is included with the product. Of course, my hair will be tied back next time…

I hope this helps someone make a more informed decision on purchasing this product.

Great Alternative to Standard Nail trimmers August 12, 2025 Color: B-dark BlueVerified Purchase I've been using this for a couple of weeks. I have two medium-sized dogs, and I get nervous trimming their nails because they will jerk their feet. I don't want to cut them, so I let them stay a little longer. This grinder is a much safer solution because it won't hurt them if they jerk around. I've been using the grinder for a few weeks, and they don't seem bothered by it. I was able to grind their nails to a much shorter length than I could do with the standard trimmer. To get them used to it, I was only doing it for a few short minutes each time. They don't run when I pull it out (they did with the nail clippers). I'm also able to grind the edges to keep them from scratching me or the furniture. It's not loud or obnoxious, and my dogs are not afraid of it, although they have only a short window of tolerance for me to mess with their feet before they get figity. It grinds the nails quickly and doesn't catch or snag as it grinds, so there is no discomfort. All in all, I recommend this! Easy to use and not stressful on my dogs. 22 people found this helpful

Excellent Tool—May or May Not be Right for Your Dog August 31, 2019 Color: A-WhiteVerified Purchase I have two small dogs—a 7 pound and a 13 pound dog—the smaller, Nixie, with nails where the quick stays far, far up the nail, the larger, River, where the quick is always right at the tips of his nails.

I normally use a Pet Dremel on Nixie’s nails—and although I wouldn’t say she enjoys the process, she’s happy enough to stay in my arms, while I do a few seconds at a time on each nail, liberally praising and treating her after each dab or two at the nails. Her hair is long, but I’ve never had a problem with it getting wrapped around the Dremel shaft, because she’s reasonably passive while I do her nails...and I’ve never had a problem with rounding her nails into a smooth, comfortable shape with the Dremel, because, again, she’s reasonably passive while I do it.

River, on the other hand, is a different case entirely! He HATES the sound of the Dremel (he hates all mechanical noises), and I have to clip his nails a bit at a time, while he lies on his back, and either file them smooth with a glass nail file, or, touch the Dremel to his nails for a split second at a time, treating and praising and rubbing his belly liberally, and allowing him to get up and “hug” me, frequently, to relieve his anxiety. It doesn’t help that since he’s prone to sudden moves, and also has long hair, it HAS gotten wrapped around the Dremel shaft a few times—something that absolutely terrifies him.

So when I needed to replace the Dremel’s battery for the third time in the last four years, (they seem to stop holding charges *FAR* too quickly!), I looked around Amazon to see if there was anything else on the market that would be useful...and found the Casfuy.

After reading the reviews, and looking at the price, I figured it was worth trying it out. I particularly liked hearing it was quieter and that there was no easy way for hair to get wrapped around the shaft, as I thought this might help with River’s fears.

When it showed up, I was pleasantly surprised by how nicely it was packaged—and by how solid (for a plastic implement) it felt. I have small hands for a woman, and it felt comfortable and balanced, when I moved it around. It also came charged, so I was able to test it right away—another lovely “extra”. :)

The noise was DEFINITELY softer than the Dremel. It’s less loud than my Sonicare toothbrush, actually—but it’s higher pitched than both, and I was a little concerned about how this would affect the dogs.

Predictably, it sent River scuttling out of the room—even faster than the Dremel does. Nixie was a bit spooked by it, but she’s naturally suspicious of new things, and didn’t seem frightened, just cautious.

I thought I’d try it on Nixie’s nails first, since she’s the easy one. I used it on low, as that’s the only speed either will tolerate on the Dremel, and the higher pitch of the high speed didn’t seem like a good idea.

Well—she wasn’t keen on it...as I held her—but the real problem was that when you touch it to a nail, and the dog predictably jerks a little, the direction of the spin, plus the jerk, means the nail hits the side of the plastic cover with a loud, unpleasant noise, and that REALLY freaked Nixie out, causing her to refuse treats, and to jerk her paws from me as soon as I tried to hold one.

I worked with her a bit, finding that it was a little better if I could manage to hold my finger over the plastic edge, so that her nail would hit my finger, not the plastic, and also trying to hold her nail steadier with my other hand—but it was awkward, and after not getting very far with her, I gave up, used the Dremel, and was able to quickly finish her nails.

I did notice that the Casfuy did naturally create a rounded shape to the nail edge on the top of the nail, but it created a sharp edge UNDER the nail, which it required a bit of ingenuity to remove, by maneuvering the tool around. I can create the same shape with the Dremel, but a) there was a learning curve, as if you hit the nail with the Dremel at the wrong angle, it makes a dreadful sound and b) I have an art background, and am very comfortable and confident in refining shapes manually. I DEFINITELY think that the Casfuy eliminates the learning curve, forcing you to avoid the wrong angle simply because of where the openings in the plastic casing are, and how you have to hold it—and it does not require any special skills to shape the nail. (And the sharp edge on the bottom of the nail would be worn off quickly, through walking, if you didn’t feel confident about reshaping with the Casfuy.)

Since River has bigger nails, I thought they might be easier to work with—I can hold them steady easier, and since I work on him while he lies on his back, rather than holding him in one arm, and using the tool with the other.

Sadly—although I had no problems acclimating River to the tool when it was off (teaching him to “touch” it, in exchange for a treat), and even getting him to touch it while on, he was absolutely, in no uncertain terms, not happy about it touching his nails. There was no calm lying there while I touched his nails for a second or two, with his eyes on the cookie bowl next to him—instead, he was terrified—so much so, that he refused to even eat any treats, and after just doing a second or two on one nail, he was panting heavily, in great distress, and had to hug me, clinging to me fiercely.

I worked with him for a while, and managed to to a bit more with his nails—and the tool performed nicely on them, never caught his hair in it at all (a HUGE blessing!), and ground his rather tough nails down quickly—but the higher pitched whine, and in particular, the louder noise it makes when grinding the nails was far too intense for him in a first session.

I did work on Nixie’s nails again the next day—and managed to get almost all of them done, this time, managing to keep her nails fro striking the plastic a bit more, but like River, she really seems to strongly dislike either the sound of her nails against the grinder, or else the feel of the grinder on her nails. I wouldn’t say either dog was in pain—I was nowhere near the quick, and I never had the grinder on their nails for more than a second, possibly two seconds, at a time, so there shouldn’t have been an issue with heat—but they were both very reactive to the sound, the feel or the combination. My subjective feeling is that possibly it is going faster at low speed, than the low speed on the Dremel—and that may create a tickling vibration that is too intense for them—as neither will tolerate the high speed on the Dremel.

Overall, I would say that this is an excellent tool. It IS quieter than very highly rated Pet Dremel, but it DOES make a higher pitched noise, when it turns, and if your pet doesn’t like high pitched noises, that is something to be aware of.

It appears to be reasonably well made for such an inexpensive tool, and I love that it’s USB rechargeable, unlike my Dremel, where I lose half an outlet to the heavy charger.

It’s easy for even small hands to hold, and it creates a smoother, rounder nail tip than the Dremel will, without any particular effort on the part of the person wielding it. If you have very large hands, it might or might not be as comfortable, but for small and medium hands, I think it would feel very natural.

The charge seems to last a reasonable amount of time. I don’t know if it was fully charged when I got it or not—but I’ve done one short session on Nixie’s nails, one longer session (where I did both front paws—I rarely need to do back paws on either dog, ever), and one longer session on River’s much thicker, tougher nails—and it showed no signs of slowing down. (I was using low speed on all sessions—how well it would stand up to a bigger dog’s nails, I can’t say.)

The grinding itself was acceptable. It didn’t seem better or worse than the Dremel—but I normally use a finer grit on the Dremel, preferring a smoother edge to the nails, over a quicker grind, so I’m not judging the grinding against, say, 60 grit. (And I don’t change out the bits on the Dremel that often—so I’m used to using a worn down grit.). I feel that for small dogs—under 15 pounds, this should be more than adequate. No idea how well it would stand up to larger, tougher nails!

Where it could be improved: first—it would be GREAT if the plastic protector for it were coated in something that would eliminate the sharp crack of nail on plastic, when the nail hits it. I REALLY feel that this noise added to the trouble I had with both dogs. A rubber or silicone coating would be great.

The other improvement is more a “nice to have”—and that’s the addition of a very bright LED somewhere around the tip, that can be changed out, when needed. I would pay more, to have this feature—as, particularly for dark nails, that extra light would make it easier to see where the quick is.

I’m still not sure whether or not I will ultimately be able to use this on my dogs. I’m used to training slowly, and conditioning a frightened dog can take time. It took a year of training to get Nixie to allow me to scale her teeth—but I got there. And it took almost three years to get River to the point where he would let me touch the Dremel to his nails after they’d been clipped—sometimes. (We may have had a setback, after the session with this tool, unfortunately! :/). I *suspect* that I can get Nixie to accept this more calmly with a few months of training—if the reason she dislikes it is noise, not vibrations. If it’s vibrations, well, four years of training has failed to get her to accept the high speed on the Dremel—so I assume it would be the same here.

River may or may not come to accept it within a year or so of conditioning—and it might very well be worth it, to eliminate the risk of his hair getting caught in it—but he also might be reacting to the vibrations—in which case, I’ll just wind up passing it on to someone else.

No product is perfect for every dog—and the jury’s still out on whether or not this will work for mine...but the product itself has a LOT going for it, and for the low price, I’d definitely recommend trying it. :). (Just don’t force your dog—and if you REALLY want this—or any other method of nail grooming to work—keep in mind that it can take a year or more to condition them, if you have a really fearful dog! Patience, gentleness, and not forcing are the key to success! :))

Great device but you need patience & treats at first January 2, 2020 Color: B-dark BlueVerified Purchase Our dog's nails have gotten out of control. I've been ill over the past few years and we haven't been able to take them on the long walks we all enjoy, walks that also help to keep their claws in check.

We have 2 dogs, a boy & a girl, with completely different nail types. Our lab-mix has traditional nails; the quick is easy to see, the nails aren't thick, and they're easy to grind down. We also have a coonhound who has thick black nails that are closer to talons than claws. Her nails are difficult to trim no matter what method is used.

The lab-mix's nails are a dream to grind down with this device while the coonhound's nails are a nightmare. The hound's nails are so thick that they don't fit well in either of the openings on the device and make it more difficult to use on her. This also means she has an unpleasant experience no matter how comfortable we make it for her.

We do have a few ideas that may help if you're new to this. They're our own trial and error tips; we learned each one having never used something like this on their nails before.

Keep in mind we're not professionals and this is not expert advice. We're providing tips on things that we have found to be. Neither of our dogs is aggressive or has any behavioral issues, if your dog(s) have these issues you may want to consult a trainer or your veterinarian before purchasing this device.

Here are things we've learned in the past few weeks while using the nail grinder:

• Trim the fur/hair around and in between the dog's toes before you first use the device on them. You definitely don't want to get their fur or hair stuck in the grinder.

• Go slow, use the slower setting to begin with, and offer plenty of treats. Even if your dog is fine with the device you still should keep treats handy so that your dog always associates the device with something good.

• Pull all of YOUR hair back with a ponytail holder, barrettes, etc. After using the grinder a few times I leaned in to get a better look. At the same time a chunk of my bangs fell forward and of course got caught in the grinder. I'm glad it was my hair and not my dog's fur! My hair was pulled back into a bun but I didn't secure my bangs.

Don't be me, be smarter than me!

• We started out leaving the device uncovered, but turned off, on the coffee table, couch, and even the floor so they could get used to seeing and smelling it.

Then we'd turn it on and just hold it or pass it to one another. We always ignored the dogs, making sure to look away from them specifically, so as to not acknowledge their reactions. At first they were obviously uncomfortable with it as they'd get up and leave the room. Eventually they began to ignore it.

•Tip: don't try to leave it on
something that can amplify the
sound of the motor such as the
coffee table.

•Tip: If you have an electric
toothbrush this is a great training
tool before you ever buy a nail
grinder. Brush your teeth as you
walk through the house; ignore
your dog, don't look in their
direction, but make sure to watch
out of the corner of your eye. If
they don't show any reaction try
sitting on the couch or floor while
brushing. If they seem a little
uncomfortable give them a treat &
a pet/scratch for reassurance. If
they walk away do this a few times
a day keeping treats easily
accessible. If they stay in the room
toss them a treat, f they take a step
closer give a treat, if they show any
little sign of making progress give
them a treat.

Make brushing your teeth a positive
experience for your dog. I bet you
never thought you'd read that
sentence...I never thought I write it
so we're on the same page!

• If you have more than one dog make sure that you use it on each dog when they're alone; at least at first. Make sure that your other dog(s) can't get in the room. If they freak out they may cause the next dog, who might otherwise remain calm, to also freak out when you try it on them.

Alternatively if one of your dogs is fine with the device being used on them and you have another dog who is less than fine with the device being used try trimming the calm dog's nails first, in front of the nervous dog. Do this every time so that your nervous dog can see the calm dog's lack of reaction.

If you have someone else in the house who can provide treats to both dogs, and especially provide treats and reassurance to a nervous dog, this would be the ideal situation.

If not try to take at least one break per paw (I do it after the first 3 nails are done) to give treats to both pups and try to reassure your nervous dog...though at the least take a break before beginning the next paw to dole out treats and love.

• Treats are big, I'm sure you've figured that out by now. Have treats handy, as in they're out of the packaging and (if needed) broken down into bite size pieces and in a spot where Spot can't get to them.

If your dog is a fan of yogurt or peanut butter try smearing some on a plate and letting them go to town while you work. If you can't find a comfortable angle to work at, for you or Fido (you both need to be comfortable but it's most important that Fido is comfy), using this method try smearing the peanut butter on a wall or the side of something like the bathtub. I don't think it'll work the same with yogurt.

•Tip: BEFORE doing this on a wall or
other surface make sure that you
test an inconspicuous area to make
sure that the oils don't leave a
permanent stain. I refuse to take
any blame for a new and
permanent, oil spot because you
didn't think to test it first.

• If your dog is tolerating the device but is obviously not happy/comfortable try doing one nail and stopping. Make sure that you give a treat immediately after you pull the device away. Always make it a happy experience.

•Tip: We always begin AND end with
a treat when trimming our dog's
nails. We want both of them to see
it as positive every time.

Overall keep the experience as positive as you can and try not to get frustrated...easier said than done sometimes.

We've been using the nail grinder for a few weeks now and one of our dogs has no issue with it, though he started out nervous. By the second week he had no problem with it.

Our other dog still stands up and walks out when she sees it. We keep it on the coffee table at all times and all she has to do is notice it and she leaves. I can say that she has stopped shaking and peeing when we use it on her...that's the extent of her progress. If given the slightest opportunity during the process she will try to walk away. Distraction is key with her. I'm not sure that she'll ever be okay with it but I know that she'll get better at tolerating it.

Again, we are not professionals in the dog grooming industry. The tips and tricks listed above are things we've learned from our own experience. If you are unsure about using this device at all please contact your veterinarian or a trainer. If you don't have a trainer that you currently trust please make sure that you get referrals from others.

I can never get them as short as I’d like them because and wanted something that could help me file them down. This was the perfect tool to do that. And for filing down the edges when she chews on her nails and cause them to splinter.

I tested it out on my own nails first and was impressed by how little it vibrated the nail during use. Easy to clean, too!

Good quality for the price. September 11, 2025 Color: A-WhiteVerified Purchase I always struggled trimming my good boy’s nails with clippers, but I decided to give a dremel a try. It was the biggest relief to be able to finally trim his nails easier, without him pulling his paw away, or risking splitting his nail or cutting his quick.

It’s life changing for a pooch who’s not afraid of some buzzing and their nails being touched.

I prefer this trimmer over a standard nail cutter any day June 27, 2025 Color: D-BlackVerified Purchase Why did you pick this product vs others?: I chose this nail trimmer because I did not want to continue using the traditional nail clipper for dogs. I have a dog that is solid black, which means that her nails are solid black. I am not able to see the quick of her nails, especially when the dog, not liking the fact that she is being held and doesn't want her nails clipped, will not be still in the slightest. I used the directions provided by YouTube videos so that the dogs could acclimate to the sound and the vibrations, and using treats along the way, I was able to get them used to the process of the trimmer. I also have bigger dogs (German Shepherds), and they are universally opposed to having their front paws messed with in any way. With training, this worked wonderfully with them. This trimmer enabled me, with time and training, to get my dogs used to the sound and feel of the instrument, allowing me to trim their nails when needed with no issues. They lay on the floor at my feet and let me trim their nails, provided I dispense the occasional treat during the process. The only thing I don't like about this is how long it takes. You will have to trim the nails regularly; otherwise, you and your dog will be sitting there for a long time trimming nails, and your dog might get impatient. Your back may yell at you as well. But I still prefer this over a standard nail cutter. One person found this helpful

Dog nail grinder - works on my dog that hates having her nails trimmed. July 10, 2025 Color: B-dark BlueVerified Purchase I waited to write this review until I used it a few times. The dog I use it for is a medium size with black nails. Someone dumped her down the rural dirt road I live on over 10 years ago, and the only issues we still have with her is that she absolutely hates anyone messing with her feet. It has taken a lot of patience and work to be able to touch her feet to look at her paws for thorns or any issues, and before now, we had to take her to the vet to get her nails trimmed. The vet recommended the pedipaws brand of grinder, but it broke after 2 uses. We bought an expensive nail grinder, but it was difficult to get to her dew claws. We finally found this gem. It does make some noise, but not much. Her nails just fit in the groove on the side of the grinder, so I don't have to worry about grinding the wrong place. It takes us many times and lots of treats when trimming her nails, but we don't have any trauma or violent jerking that we used to have. I highly recommend this nail grinder for anyone with a dog that gives you issues when trimming nails (especially ones with black nails). I usually do 1 to 2 paws at a time, going over the nails several times on a paw before moving to the next one. This ensures I don't grind too long at one time. Highly recommend. 4 people found this helpful

Game changer right here! August 8, 2025 Color: B-dark BlueVerified Purchase This is a game changer. The whole time I have been stressing about my Chihuahua’s claws because she gets so stressed whenever I try to trim them, clip them, grind them, whatever. She cries and squeals, and whimpers and makes as much noise as she can. UNTIL NOW! This nail grinder is so quiet she almost falls asleep in my lap and doesn’t even flinch when I grind her nails until now with the Casfuy! The diamond drum bit does an excellent job of grinding her nails down as opposed to the replaceable files I used to use. The best part is the super low noise and vibration - that’s what stressed her out the most and scared her. Not anymore. So now I don’t stress about it at all. I wish I had this from the very start instead of scaring my baby every time I needed to take care of her! This is a must for any dog owner - there are 3 size ports for claw sizes too. I can’t believe how quiet yet powerful this little piece is! Customer image 7 people found this helpful

So effective on all three of my dogs! August 29, 2025 Color: A-WhiteVerified Purchase My dogs hate having their nails clipped and I must admit every time I do it I end up drawing blood on one of them, it's a mess and the dogs freak out about it, it's just all around no fun for anybody. I also read that clipping their nails causes many little breaks to their nail that never heal over time.

This nail file is electric, very quiet and is super effective. Even My Little Chihuahua who has a meltdown over getting her nails done, once she realized it didn't hurt, sat still for it!

The best purchase ever for my dog, no more stress, no more pain! August 5, 2025 Color: PurpleVerified Purchase I’ve taken my dog to three vets, they tried trimming his nails and every time my dog was bleeding. Las vet gave us medication to help him be calmed, however, it didn’t work and he was hurt for the third time. I decided to purchase this item and give it a try, and worked perfectly fine for me. Of course at the beginning my dog was afraid but once he understood the assignment and realized that it doesn’t hurt, he was relaxed.

I used it today for the first time, his nails are not perfect yet but it’s a huge progress!.

I can do it by my self and my dog trusts me.

I highly recommend it! 100%

Quiet and effective. July 27, 2025 Color: B-dark BlueVerified Purchase Quiet on low speed, not too loud on high speed. Grinds the nails down very quickly on high speed. I do it in short bursts to avoid possibly creating heat. My oldest dog is the most chill with it and the others watched with interest. Most of them showed less hesitance in subjecting themselves to this strange new thing mommy uses when they saw their older sibling getting the best treat afterwards. Occasional stutter from the nail not connecting well with the grinder. I'm getting better at avoiding that by making sure I have a finger on the nail to apply light, even pressure. Only the youngest of the pack refuses to have any kind of object coming near her nails. Chihuahua. 2 people found this helpful

Great for nail trimming. August 4, 2025 Color: A-WhiteVerified Purchase Absolute best machine for animals who hate getting their nails trimmed. It was an absolute nightmare before but no longer. The machine makes very little noise and easy to handle. *NOTE I suggest removing the guard (used for little/large nail tips). I was using it and my dogs fur caused her nail & fur to slide into the guard getting tangled. I was able to untangle it all but it was really scary. Because she was squirming, I was afraid she'd rip off nail. Since I've removed the tip, this is no longer a problem.

My ANXIETY of Trimming My Pup's Nails = GONE! December 3, 2020 Color: B-dark BlueVerified Purchase I am in SHOCK at how much quieter this is than the "as seen on TV" one that I got and have been using for the last 5 years on my Golden Retriever!!!!! She cannot stand the other one! Her nails have gotten soooo long and I was told by a friend that THIS one was going to solve all of her anxieties about getting her nails trimmed. I was skeptical, so I held off. However, In July, we brought home a new angel....a Cavalier King Charles (the largest of the toy breed...but he is so teeny tiny). We tried the "other brand" on him because HOLY COW his tiny nails are so sharp and grow incredibly fast! They are small and if I don't trim them, they absolutely tear up our legs. OUCH! WELL, let's just say that the other brand absolutely terrifies our sweet ruby baby boy! It's MUCH TOO LOUD for his little ears, and the grinder is very rough and rips and tears at his little nails. Needles to say, it does not leave them smooth. So, even when they are trimmed down, they are still very sharp and I can hear them snag on the carpeting. I know it annoys him when his toenails get caught on our floors..poor baby.

Well, this Casfuy Dog Nail Grinder has changed my life.... And it was LITERALLY just delivered today! Haha! I've already done both dogs nails and neither of them squirmed away! I got them used to the sound of it before using it and lay it on each of their feet (w cap on) so they could feel the vibration and kept giving tiny training treats for not running away and praising them. They were not scared when I started and the diamond grinder was so gentle on their nails and didn't overheat... Which means they never pulled their feet away! I would not hold it on long enough at one time for it to create that kind of heat though. I do small taps on my Cavalier especially just to be careful. I kept giving both dogs training treats throughout the process and it was done before I knew it! My Golden is 11.5 yrs old and she is running around the 1st floor with MEGA ZOOMIES right now because her sweet, precious feet don't hurt anymore! Her nails were SO LONG and she hasn't let me trim them in forever. They had begun to curl under and she couldn't run anymore because she was in pain and I think she was smart enough to know one false quick turn while running would make her accidentally rip one of her toenails off. She's been so inactive because of it and it has broken my heart. So, once I realized the other junky grinder (which was supposed to be the "BEST EVER") was not a good took for our new puppy either, I decided to trust my friend and order this one. Best investment I could've made for my babies! I'm terrified to use clippers (I had a bad experience with accidentally cutting too far down and got the quik on our 1st Golden many years ago and have refused to use them ever since. I don't ever want to put any of our pets through that pain again. I also can't afford to constantly take them to the groomer/vet to get their nails trimmed. They grow so fast and it get REALLY EXPENSIVE when you add it up over just a couple of months! This nail grinder has taken my anxieties away from trimming my own dogs nails and that is HUGE! I'm tearing up watching them zip around with energy and I can tell that my Golden is no longer in pain..... She is literally glowing with bliss and having fun finally being able to run around with her "new" baby brother! Thank you, Casfuy, for making such a gentle product for my babies that cured my fears of trimming their nails on my own! I HIGHLY RECOMMEND THIS PRODUCT!

My dog approves this message February 22, 2025 Color: A-WhiteVerified Purchase My dog does not like getting his nails trimmed with the clippers, and I have a hard time seeing the quick on some of his nails…which has ended up in a few not-so-pretty incidents. This nail grinder has worked really well for both of us. I’m able to take off a little at a time which makes it easier to know when to stop. It leaves his nails with a nicer, smoother finish and doesn’t cause them to crack apart like the clippers sometimes did. My dog doesn’t seem to mind this method at all either. It has a slight buzzing noise, but it’s fairly quiet and doesn’t scare him. He will lay down and go to sleep while I trim his nails with this. I will say - this takes longer and can create a lot of nail dust which makes a bit of a mess. Definitely worth it though if your dog will accept this method over the clippers. Takes me about 20-30 mins. I highly recommend wearing a mask to avoid breathing in nail dust. Have a wet paper towel to keep dust contained as you go. When it’s nice out I find it easier to do this outside. I have a bigger dog so I’ve also found its easier to remove the black guide cap on the grinder entirely when I do his nails. My only complaint is the battery seems to die quickly. Every so often it will die before I have all of his nails done and then I have to wait for it to charge. Otherwise I definitely recommend this!
