Nail grinders gently file down a dog’s nails rather than cutting through them, and they leave a smooth edge. There is a significant learning curve to using a nail grinder, and dogs must become accustomed to the vibration and sound. After mastering the safe operation of a nail grinder, many pet owners find them easier than nail clippers, and compared to using traditional nail clippers, you’re less likely to accidentally cut the quick (the vein that runs inside the nail), which is painful for your dog and can bleed profusely. Many dogs also find nail grinders less scary than traditional nail clippers as you gently grind a little of the nail at a time until the nails are short.
