My english bulldog is always using her dew claws to permanently scratch your legs and digs at the ground while running in place if she is on her leash and sees another dog or person. The last two times I clipped her nails which are normally clear to white colored I noticed both of the nails were cracked. This isn't the first time either I've noticed this. One of the nails just grew out with no problems. The other however cracked more and turned black. She doesn't act like it is hurting her at all. My husband wants to take her to the vet and have it checked out. I was wondering if we should just have it removed. She is always cracking/splitting them and they are the worst nails when she jumps on you for scratching your legs up. Does anyone know how much it might cost? She is almost 2 years old and around 49lbs.
