I know this may sound silly however I was walking my 10 month old CC with a friend the other day and she says "wow, does he ever have a wiggle when he walks, have you had his hips looked at"? Because I am with him everyday I guess I have not really taken a concern to this or did I think it was unusual. Should I be concerned? At what age can hip issues be detected? I realize only a vet can determine whether or not there are issues but I would like to know your thoughts. Thank you...
