My baby (1.8 yr old GSD) will be getting x rayed this Friday. He has had this weird back legs lameness as a puppy. So 2 months old. We were concerned but were told that we’d have to wait til he’s older to check. Well it’s been over a year and some change and his hind legs lameness has remained. He already deals with dog reactivity and general anxiety but we have limited exercises we can do due to his legs. He can’t go over 10 mins of running/ playing ball/ anything that uses his legs too much because it tires him out completely. To the point his back legs become weak and unsteady. I’m just hoping it’s not DM or anything worse. Anything helps! Thanks
