We regularly trim our toenails; if we didn’t, they would cause all sorts of problems and affect the way we walk (not to mention the problems we would have trying to get our shoes on). Well, the same applies to your dog (but without the shoes).
When your dog’s nails become long enough to make a tapping noise on hard floors, it’s time for a trim. If you leave the nails to grow, they may cause their toes to splay out and put uncomfortable pressure on their legs and feet. Hard surfaces can also push the nail back up into the nail bed, which can cause infections.
Regardless of this, it’s not a good idea to grab some clippers and chop the nails off yourself. If you take too much of the nail, it can cause your dog even more pain. This is one situation that is best left to the professionals. An experienced dog groomer will have the expertise to trim your dog’s nails correctly to make sure their feet stay healthy.
