Buying Guide

If you are looking for a nail grinder for your dog, you want to be careful to choose the right product. Making sure your dog’s nails are taken care of important is important. You don’t want to accidentally injure them as you are working, so you’ll want to carefully consider the different options you are considering.

Bit Material

First, consider the material used for the different grinding bits. Look for products with a strong and powerful tip that will last for a long time. A diamond grinder is a great option to consider since it will be stronger and more powerful than other bit types.

Number of Bits Included

Next, consider the number of bits that come with your grinder. You’ll want a product that includes a variety of bit sizes for different types of nails. This can help you ensure you are using an appropriate product for your dog’s nails.

Safety Guard

A safety guard is a very important feature to look for in a grinder. A safety guard can help you make sure you don’t grind your dog’s nails down too far, which could end up injuring them. Some safety guards are also designed to help catch some of the dust produced by grinding your dog’s nails, which can simplify clean up after you’re done.

Speed Settings

You will also want to look for a grinder that offers at least two different speed settings. Being able to control the speed is important because it can help you modify what you’re doing for different nail types and lengths. If your dog’s nails are longer or thicker, you’ll want to use a faster speed, but if your dog has thinner nails, you’ll want a slower speed to make sure you don’t go too fast and grind off too much of the nail.

Noise and Vibration Intensity

If possible, you’ll also want to try to find a product that operates relatively quietly. If the grinder you select is too loud or vibrates too intensely, it may scare your dog, which will make the task of grinding their nails that much more difficult.


Most nail grinders are battery operated and have a rechargeable battery. Try to find a product that will recharge quickly and has a battery that will last a good amount of time before needing to be recharged.

Design/Ease of Use

Finally, think about how easy it will be to use the grinder. Is it well-designed and lightweight to help you hold it and control it as you work on your dog’s nails? Will it be comfortable to hold in your hand?

Is it safe to grind my dog’s nails?

Yes, using a nail grinder is safe, as long as you use it correctly. When trimming or grinding a dog’s nails, you want to be sure not to go too far down that you tear the “quick” of the nail, as this could injure your dog. Unlike clippers, many grinders have a safety guard that can help you make sure you don’t grind too far down.

How often should I grind my dog’s nails?

Since every dog is different, the exact amount of time between nail grinding sessions will likely differ. Most dogs will need to have you grind their nails about every month or two. However, your dog’s age and the types of environments where they spend their time can impact how frequently you’ll need to trim their nails.
