What kind of dog is he? He might have hip dysplasia and a trip to the vet might be needed. Usually big dogs get it and it is hereditary. German Shepards, Dobermans and other breeds tend to get it. I had to put down one of my dogs because of it..
But it could be some other ailment???
he isnt big. he is one of our Jack russells..thats why I dont get what happened
