I know we had a Shepard and Husky mix on them for a few years before he died. Our vet recommended them as pain relievers. He had the dog on 8 pills a day, 4 in morning,4 at night. I know the amount startled me too but in dogs, thhey go by weight of the dog, different than people. Our dog had that hip displshia at 5yrs old and had bad joints since the operation. Our vet said safe for dogs. People, no. 8 is too much.
