My grandma had to have a service dog, and at the time she had a pit bull that was only 2 years old. They trained her dog to be one because she didn't want any other dog, and he was the most the loyal loving dog I've ever met. I just want to punch the people that thought up this idea. What will they do when they realize every breed is the same, it's the people that do it to the dogs? GRRR!!! This is really pisses me off!
