Thanks Sarah, i will of course mention it to the vet but i am perhaps worrying unduly at this stage.His parents had good hip scores and he is fed on arden grange but he is a big boned dog and i have to keep a careful check on his weight as he is very greedy

.Whilst he seems to be painfree i will try to relax but i cant help but worry about him,he is only a baby and he loves nothing more than to run around and chase a ball.I dont want to retrict his exercise without a good reason at this stage because he loves to be active, that said, i would hate to do him further damage by ignoring potential problems.
Thanks again x
