Hello all, I don't know that this is the right section to ask this question. But my questions is that I have a Golden Retriever male 2 years old. But from three days he is limping by his right back leg. Iam not sure it is from injury or what? I gave him a pain killer Jenimol AP in half dose two time, which I have purchased from a Medical Store. After giving him the pain killer his limping problem is 80% ok. But his stomach may be upset and he vomit twice today. But he seems to be hungry. What should we do now? I have forgot to mention above he maintains good heath before 3 days. Please help.
