Thinking of buying a dog nail grinder? You’re not alone — grinders have become a safe, effective, and increasingly popular way to trim dog nails at home.
In this guide, we’ve selected four of the best dog nail grinders currently available. Whether you have a small nervous pup or a large dog with thick nails, there’s a model here that will suit your needs.
Each grinder has its own specific features. These are detailed in the guide so that you will be able to find the grinder that works best for you and your dog.
Points to Consider When Buying a Dog Nail Grinder
Before you decide which grinder to buy there are some important points to consider.
Rotation Speed
Check the range of rotations per minute. For small dogs they don’t need to be as high as for larger dogs with thicker nails. Dremel have previously recommended never using faster speeds than 15 000 RPM on nails of any size, but this will depend on the make of the grinder and the strength of its motor. Dremmel now offers a model with fixed and variable speeds that features 8000-25000 RPM.
Speed Gage
Check if the grinder has fixed speed settings or a sliding speed gauge. There are usually only two fixed speed settings, high and low. A sliding gauge will give extra flexibility.
Batteries
Keep in mind that battery powered grinders are somewhat bulkier and heavier. Also if you run out of power, unless you can change the batteries, you will have to wait for the battery to recharge before you can continue. If purchasing a battery powered dog nail grinder, give some thought to what is most practical for you; a rechargeable battery or replaceable AA batteries.
Noise Level
The higher the RPM the higher the noise level. A dog nail grinder that works well on lower speeds is your best choice if your dog is likely to be sensitive to the noise.
If your dog is sensitive to sound, quieter grinders like the Dremel 7350 or Casfuy are usually better choices.
Safety Guard
Consider whether you want to have a safety guard. A safety guard not only stops hair – both your dog’s and yours – from getting trapped, but also protects the paw, holds the nail in place and collects a lot of the dust nail grinding makes.
Corded or Uncorded
Corded models are great if you plan to use the grinder on multiple dogs or need consistent power without worrying about charging. On a corded grinder you will never have to recharge or change the batteries. However, while some people prefer it, others find the lead to be a hindrance.
Replacement Parts
Check the availability of replacement sanding drums, sanding bands and sanding stones. Sizes and grades may vary between different manufacturers. For more information on grinder attachments consult the page on Dog Nail Grinder Attachments.
