In an act of play, Tag tore the callous on his upper pad. It was sore and causing him unrest. So much so that he asked to be held all night long to make it feel better. When morning came, he did not hesitate to ask to go to the vet. He got a bandage pad and vets wrap that was aqua blue and had dark blue bones. Doesn't get any better than that.
It's all in a days work for a service dog.
