I thought I had a great idea. My boyfriend and I were going to play tennis at a nearby court and since it is entirely enclosed, I thought it would be fun to bring Chance. He had a great time chasing after the balls we missed (most of them), but then he stopped and layed down in a puddle which seemed strange. Then I noticed he was limping. I checked him all over and my heart sank when I saw the pads of his paws. There were three spots where the rough layer of skin was peeled back and just barely hanging on. Another spot appeared to be split but wasn't loose. And his claws were shorter than I had ever seen them. He has been limping for the past day and I feel terrible. I talked to the vet and all we can do is try to keep him from licking his feet so that they'll heel. She said it's a little like getting a blister. But Chance is the toughest dog I've known, and for him to limp, it must be pretty bad. I feel terrible and I just wanted to warn everyone about how rough the surface of a tennis court can be on our furry friends feet.
