I have used this previously for my dogs and found it to be a miracle worker. My 13+ year old terrier mix was having trouble gettin up and around. My husband and I dropped him off at the kennel for a 3 days stay and we premixed Hip Health into his food. We came home to a dog running to great us. We then started giving it to his younger sibling, who was approximately 10 and had prev suffered a serious leg injury. He lived to be 16 and never had issues getting around.
