Sorry to hear about Thor. I know how you feel. I was sad and shocked when the vet told me about Pnuts LP. He has 2 and 3

He limps or does the little hippity hop thing on and off, esp when its cold. He was on Cosequin but he started to get sick, like he would throw up if he didn't take the pill on a full stomach. So I had to switch him to this other supplement, its a little chewable. Works a little better, but when he was on the Cosequin he didn't limp at all!! That stuff is amazing!
