Best Dog Nail Grinders in 2020

Last Updated on September, 2022

My dog hates having his nails trimmed. He will fight to stay away from me and the nail clippers if I even try to get close to him. He is not small, but he is large enough to make it a battle for every nail on a paw. That is why I went looking for the best dog nail grinder to help him through the experience and spare my floor the dog claw marks.

The nail grinder I needed for my dog was one that he would not notice and kept me in control while I trimmed it down. A grinder is quiet, and if he is asleep often, he will not notice what I was doing. There are multiple things you should consider before you select a grinder product for your pet’s toenails. (Best Dog Nail Grinders) 

What should you look for in a dog nail grinder?

Grinder Ports

Purchasing a grinder with multiple ports is a good idea for a pet owner of multiple pets. Having multiple ports also ensures you are sizing the nails of your pet directly to the port for proper grinding and trimming. You should find a trimmer with at least three different sizes of grinders to make the trimming exact as well as quick.

Type of Grinder Ports

Most types of grinders come with multiple types of grinders ports for size, but you should also look for different types of grinders such as a sandpaper grinder or a diamond grinder, which is safer for your pet.

Make sure the grinder you select has multiple types of grinders to give your pet’s nails the best trim without hurting them and giving them the right kind of trim.

The different types of grinders usually come with the grinder, but some times of pet trimmers require you to buy accessories to get the right size for your pet.

Strength of the Grinder

dog nail grinderThere are many types of grinders on the market to choose from. While most will do a moderately good job, you need to find on that is strong from the beginning. The grinders need to be durable enough to last through multiple pet toes and for months on end.

Look for quality manufacturing components as well as multiple grinder ports to keep your tool working well for you.If you own a larger dog, you might want to find a grinder designed for larger pets as many of the grinders on the market are for small to medium-sized animals.

A larger nail requires a reinforced grinder bit to ensure the nail gets a complete trim. Often the smaller grinders are not strong enough for thick large dog nails, so make sure you are buying one that is strong enough for your German shepherd’s nails.

Batteries or Cables?

If you choose a cordless model of pet trimmer, you need to make sure the batteries are strong enough to trim through your pet’s nails before the clipper dies.

A good quality trimmer will go through several trimmings before needing a battery change or recharge. If your pet has thick nails, this can eat up batteries and cause the grinder to die more quickly.

If you choose a grinder that comes with a cable, you will not be as flexible in how you interact with your pet, but you will have an unlimited supply of power. If the grinder is rechargeable, make sure you know how to change the batteries and what kind of batteries it takes.

Noise Level

Best Dog nail grinders cover imageA lot of pets can become scared or overexcited at any type of noise. When reviewing the different types of pet grinders, there should be listings for the decibels level produced by the motor in the grinder.

A good dog toenail grinder should be less than fifty decibels of sound, so your pet is less likely to become scared about the noise the grinder is making.

Anything louder than fifty decibels may be too powerful for a small or mid-sized pet. Unfortunately, the larger your pet is, the stronger the motor you will need to grind through your dog’s nails. It also means the decibel levels will likely increase to match the strength of the grinder required to go through each pet nail.


Low vibration features when grinding are ideal for nervous pets. They are less likely to panic as you smooth down their toenails and also less likely to damage their cuticles. You should look for a model of grinder that comes with limited vibrations because of built-in mechanics that ensures the grinder itself is not loose in the handle but also controls the grinding of the pet nails.

Ease of Clean up

Part of taking care of your tools is cleaning them up when you are through using them. The right grinder comes apart easily to change heads as well as clean.

The cleanup should require little more than removing built-up nail shards and dust from the grinder heads. A clean wet cloth is most often the way to remove the dust safely from the grinder heads and moving parts.


There are cheaper models of grinders on the markets that are perfect for smaller dogs and cats; they are not always the best of quality. A high-quality pet toenail grinder will not come cheap but will cost you more for the quality.

There are very expensive grinders you can buy that will get the job done, but for an animal with thin or weaker nails, you should be able to choose a cost-effective version that will do the jobs.

If your pet has thick nails or has larger nails as they are a large breed than you will need to spend extra to buy a trimmer that has the strength to grind through thicker nails. There are cheaper large pet nail clippers; you will have trouble finding one that is good quality and has the strength.
