Hello, I am just browsing the forum and came across your post. Our dog Sam has very clicky leg(s), it sounds painful and was noticed from about 5 months. There is no lameness. It is very consistent, all the time (not just stairsor anything). We talked to our vet and he suggested we try anti inflammatory painkillers for two weeks which we did and it made no difference so the vet (who is a consultant in orthopaedics), did xrays. He couldn’t fine anything wrong but suggested cartophen (not sure of spelling) injections weekly for four weeks. It didn’t make any difference. He is only 12 months old. The vet said unless there is any lameness not to worry.
