Thanks for the replies.
Buddy is going to another vet today, the same one that did his surgery last year. Hopefully he will gives us more information and tell us what we need to do to help Buddy's leg get better. I have read about the glucosamine & fish oil supplements, that is one of the hundred questions that we will be asking his vet.
I just want to be sure that I have all the information together.
I will be using ramps for him and establishing the no jumping off the couch rules.
I'm so glad I found this forum for yorkies.
Thanks again!!
