The grinder is also surprisingly silent, which means you won’t have to worry about spooking your dog. On the downside, though, it’s the most expensive dog nail grinder on our list, but the extra cost is worth the quality and reliability.


  • Easy to use and safe
  • Two-year warranty
  • Painlessly trims your dog’s nails
  • Relatively silent performance
  • Easily replaceable Dremel sanding drums and bands
  • Its cordless portable design gives you better control and convenience of use

  • Affordable price
  • Replacement guarantee
  • Silent performance and minimal vibrations
  • Multiple convenient options for quick charging of the battery

Nail Grinder Buying Guide

Why Use a Nail Grinder instead of a Clipper

If you’ve been using a nail clipper to groom your dog’s nails, you should Consider switching to a nail grinder. A nail grinder is a portable device that uses a fast-spinning grinding stone to file down your dog’s nails. Depending on which you buy, the device may be corded or cordless, or interchangeable.

The material of the grinding stone goes a long way in determining the efficacy of a nail grinder. Most of the best dog nail grinders use a diamond grinding stone wheel. The tougher the grinding stone material is, the faster and more effective it’ll be at filing down tough dog nails.

Clippers don't leave a smooth finish, and the dog's nail has to be filed after cutting to smoothen the edges. With a grinder, you can get the perfect finish in fewer steps.

Also, clippers can be painful for a dog while a nail grinder is painless and quick. The difficulty of using a clipper is more pronounced if grooming a dog with really hard nails. With a grinder like the Dremel 7300-PT, such issues are eliminated.

Dog Nail Grinding Tips & Tricks

To get the best results, and avoid hurting your dog when using a nail grinder, apply the following tips:

  • Don’t rush the process. If your dog has long nails, don’t expect to painlessly file it all down on the first day. Instead, gradually file it a bit at a time every day. Using this process prevents hurting your dog, by giving the quick a chance to recede before you get to it.
  • File from the tip of the nail. Don’t start filling your dog’s nail from just anywhere. Start from the tip and work your way down, smoothing the edges as you go along.
  • Grip the grinder close to the spinning wheel. This will give you better control and accuracy when handling the device.
  • Make sure your dog is at ease. If your dog is agitated while you are using the grinder, accidents can happen. Have your dog sit or lie down while you use the grinder, and be sure not to hold the paw too tightly. If your dog feels you’re agitated, he/she will also become agitated.
  • Pause and continue. Grinders get hot from the friction against nails while they work. Place a grinder on a nail for no more than two seconds at a time until you reach your desired nail length.
  • Protect the fur. If your dog has long hair, take care to ensure his/her fur doesn’t get caught in the grinder’s spinning wheel. If necessary, trim the hairs around the paw before you begin.
How to Grind Your Dog's Nails (DrsFosterSmith)

How to Get the Best Dog Nail Grinder

You can get the best nail grinder for your dog by looking out for the following features:

  • Power

A quality nail grinder must have a tough grinding stone and be able to generate enough power to spin the stone fast enough to file nails quickly. The tougher your dog’s nails are, the more power you’ll need.

If a nail grinder can’t generate enough RPM to match the toughness of your dog’s nails, the grooming process will take longer, which is no fun for you or your dog.

  • Detachable Cover

A removable cover makes clean up easier and allows for better versatility. If you are unable to remove the cover, you might be unable to work on really long nails and might end up hurting your dog if you try to force it.

  • Ergonomic Grip

The more comfortable the grip on the grinder is, the more comfortable it’ll be for you to use it. At the very least, it should have a textured body that gives you a firm grip and minimizes the risk of accidents.

  • Cordless

Some nail grinders are cordless, while others are corded. Cordless versions are more convenient and let you move around with ease, but if you don’t mind being restricted to one location when doing your dog’s nail grooming, then a corded grinder is fine.

Final Thoughts

There are a variety of dog nail grinders to choose from for your best friend, but if you want one that delivers the best results without hurting your dog or stressing you, be sure to pick one from our above list of best dog nail files.

Just remember that the best dog nail file for you and your pet will depend on the toughness of your dog’s nail.
