My poor dog walks on two legs. One back one, one front one. We already spent about $400 at the vets and they want to do more tests. We just can`t afford it. I think he has degenerative joint disease. If he loses any more leg use we may have to put him down. He is 8 years old and a shepherd mix. I was giving him children's aspirin to help the inflammation but he still has problems. His muscles in those two legs have nearly gone away now. I just don`t know what else to do for him.
