There are pros and cons to using nail grinders, but overall they are very safe and effective. I have lots of experience with cutting dog nails, and I personally prefer to use clippers for just one reason - they are much faster than using a grinder.
"As the name would suggest, this trimmer is cordless. That is a HUGE benefit over other products. When you're shopping for a nail grinder, a cordless option should definitely on your list."
