My dog, Stella, is three and a half years old, I think. And in her old age (ha!) she has had something, I don't know WHAT though, growing on her foot. Ew. So she has been limping for a while now and we've taking her into the vet. They found out what it was and treated it by putting a HOT PINK cast on her left foot. This she chews on and will soon be unwound ,so over the cast, we have fitted a very flattering, knee-high bootie.
