I have already taken him to the vet about three months ago. The vet said I should go back to see him if Ace continues with his pain by the time he is 18 months old , right now he is 9 months old. And he seems to have trouble with mostly his front leg one them in particular. It breaks my heart to see him this way and the vet said that he may develop genetic health issues relating to the bones. I know this sounds stupid but i forgot the name of it. He said its a 50/50 chance he may grow out of it. But i highly doubt it seems like its advancing too soon. I dont know what to do anymore. The vet also prescribed this chewable chocolate-like vitamins to help with his joints but it does not seem to work.
