Dewclaws -- vestigial toes set on a dog's leg, not on the paw -- are mostly non-functional, but rarely do any harm. Occasionally, dewclaws are loosely attached and can become torn and need to be surgically removed. Because of the potential for damage, some breeders have dewclaws removed shortly after puppies are born.

Dog lovers need to keep an eye on dewclaws and remember to keep the nails trimmed. It's not uncommon for a veterinarian to have a dog come in for a routine visit and notice the nail on a dog's dewclaw curling around and growing back into the foot pad.

Ask your veterinarian to show you how to keep all your dog's nails properly maintained.
