Why Have a Nail Grinder?

A nail grinder is a great pet grooming tool that has a lot of advantages. Let’s have a brief overview of them.

Easier to Use than a Nail Clipper

The problem with nail clippers is that they need a high level of precision, so you don’t cut into the dog’s quick. This can be painful on your pooch and cause bleeding.

While you might still hit the dog’s quicks with a nail grinder, it’s much easier to avoid even if you have unsteady hands.

Saves a Lot of Money

Dogs need trimming every 4 to 8 weeks to keep them in good shape. Booking an appointment for nail care every 2 months can set you back quite a hefty sum in the long run.

Using a nail grinder will help you get the job done from the comfort of your home, without having to pay for expensive vet visits.

Smoother Edges

Besides costing you less, it’s also pretty efficient! Nail grinders can give you a much smoother finish than a nail clipper.

These smooth edges of the nails make it a lot easier to play with your dog without scratches and accidents. Moreover, prevent them from pinching into carpets, furniture, and clothes.

Things to Look for in a Dog Nail Grinder

While shopping for a dog nail grinder, there are some aspects that you need to keep on your radar. Here’s what you should be looking for.

Noise Level

While we can handle a bit of noise, it can easily frighten your dog. Look for a grinder than produces noise less than 60 decibels for a smoother and more comfortable session.

Dog Comfort

The secret behind the dog’s comfort is the quality of the internal grinding wheel. The better the quality, the quicker and easier the job will be for you and your pooch.

Speed Levels
