Down syndrome dog
My parents' dog is really old and can't play with her frisbee or tennis balls anymore. She could barely get up onto the couch. (She is incredibly spoiled) My mom took her to the vet and the vet recommended some expensive glucosamine and chondroitin pills for her. Those pills work wonders for their dog. She can jump onto her couch again and play for a few minutes at a time. Walks are still hard on her but she is 12 years old and it is a wonder she can go on walks at all.
