Steps for Grinding Nails

Recommended by veterinarians

. Hold your cat’s paw in one hand and gently squeeze it to extend the nails from their resting retracted position.

. Before you start grinding, determine how much of the nail needs to be grinded. Position the grinder in a way that it encircles the top of the claw, and start working from the inside curve of the nail.

. Smoothly start grinding the top of the nail – don’t apply pressure and grind in short bursts.

. Repeat for each nail. Don’t forget the dewclaw on the front paws.

    I don’t normally write reviews, but I felt this one warranted one! I have a 6 year old mini dachshund and trimming nails has always been rough!! Screaming and biting (from the dog). I’ve tried other nail grinders and she was terrified of them. I came across this one and thought I’d give it a try. It took only 5 minutes to do ALL FOUR paws! She held perfectly still and didn’t fight me a single bit!! She even wagged her tail when we were done!! Hallelujah I think we found the tool for us!!!

    My dog hates having her nails trimmed but she doesn’t mind this at all. I trimmed her nails fairly short with a regular clippers to begin with and I now use this weekly to keep them short. A little desensitization training at first is helpful. I started by just turning it on and then giving her a treat. After doing this a few times, I tried it on her nails-just one foot at a time and then I would give her a break. I did all 4 feet by the end of the day this way. She really just didn’t pay any attention to it at all. Now I can do all 4 feet at the same time and she just lays there. It works best on high. I do think it would be difficult to start with long nails and trim them short with this, but it is great used regularly to keep them short once you have trimmed them short with a traditional trimmer.

    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!), my friend recommended proyoo to me.

    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 Proyoo 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 Proyoo 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 Proyoo.)

    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! :))

    This grinder was quick and easy to use on my 3-month-old German Shorthaired Pointer. While she’s still fairly young and new to/scared of most things, she didn’t seem to be bothered at all during the filing. I used the slower setting with the bigger filing top and it was very quiet. I love the fact that it’s larger and extremely easy to hold, no slippage whatsoever! I actually clipped her nails prior to using this, but soon realized the grinder is so efficient that I can eliminate that step in the future! Her nails came out perfectly rounded with no sharp edges. Afterwards, she happily ran around the yard for hours while my husband finished building the fence, then promptly passed out for a nap once inside. She’s happy, I’m happy, outstanding product! It’s definitely a time saver and easier to maneuver than clippers.
    Instructions were easy to follow and a charger was included.
