The Best Dog Nail Grinders of 2021: 5 Options

It’s okay to admit you hate trimming your dog’s nails!

Nail trimming is one of the most frustrating aspects of pet care. First, you have to be extra-careful to avoid cutting the nails too short and accidentally hurting your dog. This is a very real possibility, as dogs have nerve endings and blood vessels within their nails. If you cut them too short, your dog might bleed and get hurt. 

Also, most dogs want nothing to do with trimming. They squirm, struggle, and refuse to sit still. This is because, while cutting nails is a natural part of a regular hygiene cycle for humans, dogs aren’t used to getting their nails trimmed. 

Nail grinders are safe and effective, but they can seem confusing to use. Fortunately, our complete guide will help you pick the perfect grinder – and we’ll teach you how to use it safely, too. We’ve even gathered up our five favorite nail grinders for 2021.

What is a Dog Nail Grinder?

Dog nails can be trimmed in two ways:

  •       Nail Clippers
  •       Nail Grinders

Clippers require a high degree of skill to use safely. You need to understand the structure of the nail to avoid accidental injury. Cutting the flesh underneath the nail, called “cutting the quick,” can hurt your dog and even lead to infection. It’s recommended that you get your dog’s nails cut at the vet’s clinic before you’re absolutely sure that you can carry out this process at home.

Nail grinders use a different approach to trim nails. A grinding drum spins at high speed. It wears down the nail. Because the drum starts at the top of the nail and works towards the paw, accidentally cutting the quick is very difficult. 

This process also helps keep the dog calm, as there are no quick cuts on their nails and the material is slowly taken off with the help of the machine.

How Often Should I Trim My Dog’s Nails?

Generally, you’ll want to trim your dog’s nails at least once every two months. However, every dog is different. Your dog might need his nails trimmed more frequently (although two months is the maximum length of time between trimmings for every dog).

Trimming needs depend on the breed of dog as well as his activity levels. Some dogs have thick, fast-growing nails. Typically, the larger the dog, the tougher and larger his nails.

How do you know when your dog’s nails are too long? Picture him standing on a horizontal line. His foot pads rest on the line exactly. In this position, his nails should be above the line. If they extend below the line, it’s time for a trim.

Also, pay attention to the sounds your dog makes. When nails are too long, you’ll hear a loud ticking sound whenever your dog walks across wood or flat services.

Focus on maintenance. Trim your dog’s nails briefly every week or so. Short, frequent trims are easier on dogs than longer sessions.

What Features Should I Consider?

Nail trimmers can seem complicated. Why is one better than any other? When choosing a trimmer, consider the following features:


Trimmers should be made from high-quality plastic. They need to be durable enough to survive an occasional drop on the floor – especially if your dog likes to wiggle.

Grinder Quality

The grinder is the most important part of the trimmer. Most trimmers use a diamond bit grinding drum. It’s strong enough to wear down nails quickly.

Other trimmers use a sanding band, which is powered by sandpaper. Trimmers with sanding bands are the least common type. They require a bit more maintenance. You’ll need to replace the sandpaper from time to time.


Choose a grinder with at least two-speed settings. The faster setting is useful for the initial trim, while the slower speeds are safer as you get closer to the quick. Variable settings allow you to switch speeds easily while trimming without having to release your hold on the dog.

Noise Level

Some dogs could care less about the noise and motion of the nail trimmer. But most dogs are at least somewhat anxious in its presence, if not downright terrified. You want the trimmer to be as quiet as possible. Most trimmers will list the decibel level produced during operation.

Power Supply

A grinder with a built-in battery charger is usually the easiest and most economical option. You don’t have to worry about buying new batteries. Simply plug the grinder into a wall outlet or USB port.

Most grinders take less than an hour to charge. Don’t worry too much about long charging times as nail trimming can usually wait a few hours. However, charging times of several hours can be annoying.

How Do I Use a Nail Grinder?

Basic operation involves seven simple steps.

  1. Gather the trimmer, treats and, of course, your dog. Choose a quiet spot free from distractions. Your dog should already feel comfortable in the selected area.
  2. Sit next to your dog or hold him in your lap.
  3. Turn on the nail grinder.

Allow your dog to investigate the running grinder as much as he likes. You want him to feel comfortable with the noise and motion. If he’s not used to the nail grinder, you might need to repeat this step several times. Simply sit with your dog and run the grinder without trimming his nails. He’ll grow increasingly comfortable over time.

  1. Hold your dog’s paw gently but firmly.
  2. Place the grinding tool against the nail. Pay attention to your dog’s mood as you work. If he starts to fidget too much, remove the grinder but don’t turn it off. Also, don’t release his paw. Simply taking the grinder away from his paw is usually enough to calm him down.
  3. When you’ve finished trimming a nail, turn off the grinder. Give your dog a treat and lots of praise.
  4. Repeat the process to trim all his nails. Try to trim all nails in one session. Walking with uneven nail lengths is uncomfortable for dogs.

What are the Benefits of Trimming My Dog’s Nails?

Nails which are too long can cause a variety of health problems. They can impact your dog’s ability to walk and run. Pain can extend through his ankles into his legs.

Nail clippers can actually cause additional problems. Clippers increase the changes of nail breakage and splintering. Grinders keep the nail smooth and uniform.

The Best Dog Nail Grinder

If you’re a new pet owner, we recommend all nail trimmers over clippers. Trimmers are safer and easier for both you and your dog.

All of the grinders on our list are effective and easy-to-use. However, after extensive testing on dogs of all shapes and sizes, we recommend the Dremel 7300-PT. It’s the best nail grinder for most breeds and ages.

Normally, we prefer a diamond bit to a sanding band. But the Dremel’s sanding band is fantastic. It’s coarse enough to wear down nails quickly, but not harsh enough to accidentally injure the skin.

Additionally, we like the Dremel’s versatility. It’s compatible with a wide range of Dremel sanding drums and bands. You can easily find the perfect drum for any size dogs. (We admit visiting the hardware store for a dog care item is a bit weird, but the wide range of options is impressive.)

Finally, we like the dual speed settings. The fast setting quickly trims even the toughest nails. The slow, quieter setting is the best option for dogs who don’t like loud noises.

Long nails impair your dog’s ability to walk and run. Keep his nails trim with an electric nail grinder. They’re safe, easy-to-use and effective. Your dog will give you a thumbs up!

The Bottom Line

Making your dog stay calm and sit still for trimming his nails can prove to be an impossible task. Furthermore, there are dangers of injury and infection associated with trimming their nails if you cut them too short. 

Nail grinding is a much safer and easier way to ensure that your dog’s nails are in check and don’t end up accidentally hurting you or someone else. Nail grinders are better for your dogs, as well, as there’s a much lesser chance of injury to their feet.
