I am new here, l have a five year old chocolate labrador Otis. Recently whilst getting off the couch, he stumbled, his back legs gave way, l took him to the vet, who said there was an issue with his hip joint and has ref ferdinando me to an orthopaedic surgeon, we have an appointment next Friday, where they will do x rays to establish what the problem is. I am quite worried and wonder if it could be his cruciate ligament, anyone know what signs there would be to indicate this? Or maybe it is hip dysplasia, he is on metacam, prescribed by the vet. I would welcome any advice from anyone, thankyou, Maggie and Otis
