The vet informed me that Chobby, my 4-month-old Cavalier, seems to have luxating patella 2 months ago. At first, I could tell that his hind legs were kinda weak. During the past 2 months, I have paid a lot of attention and cared for him. Well, it seems like his hind legs are getting better and stronger. The vet told me that he might get better, but the possibility of the problem developing is still there. A surgery is most likely necessary if his condition worsened. With this fear in mind, I would like to get some inputs from you regarding luxating patella. Humans can get extra help from taking vitamins. Can I do the same for a dog? Do you know what kind of supplement that I can give to Chobby in order to improve his condition?
