Gunner is a little wobbly in his back end when his walks. One of his hips, the left, sits slightly higher than the right. He seems to have no motion pain or issues in movement, no tripping, he just seems a little visually unstable when you walk behind him. He seems to have no discomfort on soft pressure anywhere in the area, I pressed him with my fingers today and he didn't bat an eyelash.
He did slip and fall down a hill last August, threw his right knee out. It feels a little rough if I palpitate the knee cap, and it pops audibly sometimes. Other than when he threw it out, we haven't seen any limping.
Any ideas? Is this something I should be concerned about?
