This dog is ten years old. Yesterday, he began to tremble all over, and after a few steps, he cried out in pain. He is thin and doesn't eat. What disease is this and how to treat it?
Considering whether it is a nerve problem or a joint bone problem, first look at whether the external skin is damaged or swollen. If there is nothing unusual, you have to take it to the hospital for specific film examination. If you are thin, you can use probiotics to regulate the dog's stomach and enhance absorption.
