I rescued a 12yr goldie. After a walk he started squealing when he tried to lie down and hopping on a back leg. In alot of pain. My vet gave tramadol and said xrays for likely cruciate. I used a mctimoney practitioner and after one session he was walking normally and slept all night. He had a trapped nerve. He had 2 more follow up sessions and is now fine.now use mctimoney on my younger dogs if needed.
