Looking to trim your dog’s nails? Anyone who has tried—and failed—to do the deed with a pair of traditional dog nail clippers will be happy to know there’s another option, short of heading to your vet or groomers: Dog nail grinders. Think of these like a super-powered nail file that uses friction to shorten and shape your pup’s nails.

For a successful nail grinding session, start by allowing your pup to inspect and sniff the tool first before turning it on. Then switch it on so they can get used to the sound before you start grinding their nails, remembering to hand out plenty of healthy treats along the way.

You can choose from two speeds and three ports, which makes it easy to customize the grinder to your pet's needs. Veterinarians and pet grooming professionals recommend it for novices and experts alike, thanks to its lightweight, ergonomic design that makes maneuvering a cinch.

Best Budget: Wahl Classic Dog Nail Smoother

Wahl Classic Dog Nail Smoother

You get a lot for your money with this dog nail grinder from Wahl, a 100-year old company based in Illinois. That includes two large sanding drums and five sanding bands that are easy to change. The grinder is lightweight and easy to use and reviewers like that it’s battery operated. It has one speed: 5,300 RPMs, which is on the slower side compared to other grinders. The benefit is that it’s super quiet, while the downside is that it might take longer to groom all of your dog’s nails, especially if your furbaby is a larger breed.

Best Splurge: Andis Cordless Dog & Cat Nail Grinder

Andis Cordless Dog & Cat Nail Grinder

Not only does this Andis nail grinder feature sanding bands of two different sizes (because your pup’s toes and nails aren’t all the same length), it also runs on six different speeds ranging from 7,000 to 18,000 RPMs. This helps ensure that it will work on all sorts of dogs (and cats!) by being slow and gentle—or quick and powerful—enough to get the job done. And it’s as easy to swap out the bands as it is to operate this ergonomically designed grinder, which has a rechargeable lithium-ion battery that can run for up to three hours on a single charge. For convenient transport, it all comes housed in a hard plastic carrying case.

Its 45-degree angle prevents the likelihood that you’ll cut too quickly, while its clear cap nail guard helps capture nail dust for less of a mess. The grinder is cordless and has an ergonomic design, so it's easy to control and handle. Just make sure to start at the slowest speed, then work your way up as needed.

Best for Dark Nails: FURminator Nail Grinder for Dogs and Cats

FURminator Nail Grinder for Dogs and Cats

One of the top advantages a nail grinder has over a pair of clippers is that it can give your dog’s nails a soft-rounded edge that won’t snag on furniture or clothing.

With two different speeds, it works quickly, which means you can get the job done in a jiffy (ideal for dogs who don’t like having their paws touched).
