Over the past few months Harley has been having massage therapy because we noticed she seemed stiff in her back legs at times. The therapist has told me that some of the muscles in her legs had stuck together, but is slowly easing. Also, she has had a lot of tension in her back and legs. She gets walked for an hour to hour and a half every day and we do agility weekly which she is very good at. She is a very fit girl and doesn't ever show when she is in pain. We have been to the vet as she had 2 episodes on limping and they suggested rest and see how she was (Sep & Nov 2016). The vets have said they can't feel anything, but are hesitant to X-ray her as she is still quite wary at the vets. The massage therapy has helped, but we are still have periods when she appears to be quite stiff and I think she is in pain, but as said earlier, really doesn't show pain. My question is, should I push for an X-ray? Or does anyone have any other suggestions?
