Well I went to get a second opinion ... The vet said that there is no movement in the knee cap and LP is not the cause. She was certain. She moved his back legs in every direction possible and felt no movement nor caused him any discomfort. When he gets his teeth cleaned next month they are going to x ray his back legs to see exactly what's going on. She said that he could very well just walk funny due to his physical makeup. But it'll give us piece of mind thru the x rays |
