It’s important to keep your pet’s nails to a reasonable length, which typically requires trimming every four to six weeks. Or you can get your dog or cat used to getting their nails cut by trimming a single nail nightly.
Pet nail grinders work differently than nail trimmers, by filing down nails rather than cutting them. A great pet nail grinder operates quietly, with minimal vibrations—both factors that can determine whether or not your pet will get scared by the device. If you’re new to nail grinders, it’s also worth looking for a device that has lower settings that allow both you and your animal get used to it.
“Professional nail grinders have high speeds that might cause injury to animals if used by inexperienced groomers.” Dannie Stewart, of Kelly’s Pet Boutique in East Lansing, Michigan, told The Spruce Pets. “For use at home, I recommend a grinder that has a low speed setting and low vibration so as to avoid the breaking off of nails/claws or otherwise causing injury.”
Our favorite pet nail grinder is the Dremel 7350-PET 4V Pet Nail Grinder, which operates quietly, doesn’t vibrate much, and has a built-in rechargeable battery. But there are other nail grinders we also love that may work even better for your cat or dog.
Here are the best pet nail grinders.

What to Look for in Nail Grinders
Nail grinders for pets will either have a cord to plug in or be battery-operated. There are advantages and disadvantages to each type. For example, cordless nail grinders are easier to maneuver, but you must remember to charge them sufficiently prior to use. Corded nail grinders can be used anytime with no need for charging, but you’ll be tethered to an electrical outlet while you work on the animal. To offset this problem, it helps to seek out an extra long cord on your nail grinder.
Pay careful attention to how pets respond to the buzzing of a nail grinder. While most don’t mind a gentle vibration and quiet whirring noise while it’s in use, they may become nervous around especially loud sounds. If you can obtain a nail grinder that’s advertised to run quietly with minimal vibration, or one with adjustable speed options, you’ll increase the likelihood of your working successfully with various pet temperaments. If your pet has trouble adjusting to the nail grinder, consult your veterinarian. There are ways to work your dog’s favorite treat into the nail grinding session to help them relax, for example.
If using a nail grinder is new to you, be sure to take the time necessary to master its safe operation before starting on pets. Also, look for nail grinders specifically made for pets, not an all-purpose type. Carefully read the packaging to see if there are any built-in safety features (such as safety caps or stop features), written instructions, sanding bands, and/or discs. Look everything over, read all instructions, and familiarize with the grinder’s components before you start grinding any nails.
How do you grind dog nails?
Stewart says his team usually (but not always) trims animals’ nails with regular nail trimmers before getting started with the nail grinders. He explains that this is because the groomer would be grinding for a really long time using just the grinder by itself, and this could make the animal's nail hot, causing them great discomfort.
Keep in mind there’s a significant learning curve to using a nail grinder, and animals must become accustomed to the vibration and sound. On this note, Stewart adds that he likes to move the nail grinder around on the nail's surface gently and evenly as he works, so that there isn't a lengthy vibration on any one spot, which could be uncomfortable or even painful to the animal. He aims for the nails to have an overall rounded surface, grinding off any sharp edges as he works.
Are all nail grinders better than clippers?
Stewart feels that grinders are better overall than clippers because you can shorten the nail more easily without the worry of injuring the animal. This is helpful especially for people who are new to trimming nails, as novice trimmers often cut nails too short, causing pain and even bleeding. This is far less likely to occur when using a grinder.
Do nail grinders hurt dogs?
Grinders can hurt animals if not used carefully, as mentioned above. It's important to move the grinder evenly over the surface of the nail, not allowing it to remain on any one section for too long. It's also important to pay attention to whether the grinder is getting too hot or causing too much vibration in any one section as you work.
