I have two dogs. The black dog is Roxy and the other one is Tisy. Roxy is 10 years old. Tisy is 8 years old but he is almost 9 years old. We got Tisy when I was a baby. When Tisy was little Roxy got attacked by three big dogs and she had scratches and bites on her. Tisy was chained up on his kennel and so Dad let him off and he head butted one dog and knocked him out cold. He was the size of guinea pig.
