Best Dog Nail Grinder Buyer’s Guide (plus helpful tips)

The Best Dog Nail Grinders

Clipping a dog’s nails can be a real hassle especially if they’re not cooperative with the process. And even if they do tolerate having their nails clipped, it usually leaves them with rough, even sharp, nails for a few days. 

If you’re just looking for the best nail grinder, we recommend the Hertzko Electric Pet Nail Grinder. We’ll break down exactly why we think it’s the best option a little further down.

What Exactly is a Nail Grinder?

A nail grinder is a tool used to groom your dog’s nail as well as a nifty alternative to nail clippers. There are various types of nail grinders on the market today made by many different manufacturers. Nail grinders, which are run by a motor, have a grinding attachment that grinds away at the nail.

The attachment is made of sandpaper and works in much the same way as sandpaper. While the term “nail grinding” may sound complicated, it’s actually a simple and, often less stressful, method of trimming your dog’s nails.

Pros & Cons of Using Nail Grinders

Nail grinders are a great way to give your dog a pedi quickly and without the pain often found with nail clipping. There are a few advantages to using nail grinders as opposed to nail clippers. Like with most things, there are both pros and cons.


  • Easier to tolerate for anxious dogs – If your dog has had a bad experience with nail clipping in the past, he’s probably ready to freak out at the very sight of nail clippers. This is a new experience for the dog, and you may have more success getting your dog used to grinders.
  • Ideal for thick nails – Dog nail grinders work much better, quicker and with less discomfort on thick nails.
  • Give smooth, rounded nails – Nail grinders cannot only round out your dog’s nails but will also give them a smooth finish. Nail clippers have a tendency of leaving the nails rough, which makes for easier snagging on the carpets or scratching things.
  • Quicker than nail clippers – It may seem like grinding would take longer, but they don’t because it’s a smooth operation, especially once your dog gets used to the process.


  • Touching the quick still possible – While hitting the quick is more likely with nail clippers, it can still be done with nail grinders if you’re not careful. Usually, this experience is what turns dogs off to having their nails clipped.
  • Grinders can be loud – Dog nail grinders are not quiet and may intimidate your dog if the dog isn’t accustomed to loud noises.
  • Can be a messy process – Grinding the dog’s nails can be smelly and dusty, so you may want to do this outdoors and possibly wear a mouth mask.
  • More expensive – Dog nail grinders cost more than clippers.

Things to Be Aware of When Using Nail Grinders

Nail grinding is often the perfect solution for dogs that don’t like nail clipping. There are a few things to be aware of with nail grinding. Some dogs are just very sensitive about their nails being touched. You may want to let the dog get used to the noise before you actually start grinding the nails.

Never force the issue with the dog. A dog will seldom “get used to” something that frightened him or caused him pain. You should also pay close attention to what you’re doing because it’s still possible to hit the quick and cause the dog pain.

Dogs have very good memories! They’re not much different from you or me in that respect.

Imagine if someone caused you to bleed and feel pain while clipping your nails! Wouldn’t you be apprehensive about letting them do it again? I know I would surely think twice!

Tips When Grinding Your Dogs Nails

Here are some tips to make the nail grinding process a little easier for you and your dog.

Start at young age

The younger the dog is when you begin nail grinding, the easier it will be and the quicker he’ll adjust.

Grind a little at a time

Take your time grinding so in case you do grind too much, there will be little harm done. The quicker you are, the less chance the dog will become antsy.

Make the dog comfortable

The more comfortable the dog is, the less he’ll notice or care what you’re doing to him. Practice holding the dog’s paw in different ways and choose the way that seems to have the dog the most comfortable.

Watch the grinders

Nail grinders tend to get hot quickly, which is why you only want to hold them against the nail for a short time.

Watch fur & hair

If the dog has long hair, make sure it doesn’t get caught in the grinder attachment or you could have a real problem!

Are Nail Grinders Difficult to Use?

Nail grinders are relatively simple to use, especially if you’ve read the directions! Hold the grinder in an upright position as close to the top as possible for better control. Hold the dog’s toe gently, making sure to not squeeze it. Grind across the bottom of the nail, moving slowly in from the tip of the nail. You can also smooth the rough edges at this time.

Press and release the grinder in small increments to prevent it from overheating and to not bore or frighten the dog. If you do this once a week, your dog’s quick will start to recede, and your dog’s nails will appear to be short almost at all times. If you’re the type of person who prefers to see something rather than read about it, here’s a short video on how to nail grind your dog.

Choosing the right one!

Choosing the right nail grinder for your dog can be a big decision. Who enjoys spending money on products just to discover they need to be replaced because they weren’t everything you were promised?

After reviewing a few of the top nail grinders, I find that the Hertzko Electric Pet Nail Grinder is probably the top choice. Many consumers like to stick with name brands. That was not the reasoning behind my choosing the Hertzko because they’re all name brands!

Dollar for dollar, they were similar in price and all somewhat affordable. I chose the Hertzko because it seems to garner the best customer reviews and offered the thing dog owners want most: good performance, convenience, ease of use and good price.

It’s not a professional nail grinder but operates with an efficient and quiet operation as a professional tool. It very well could be everything you’ve ever wanted in a dog grooming tool designed to keep your dog’s nails looking smooth and professionally groomed!
