he has already been to the vet for it. We tested fecal, urine, blood, and brain pretty much. Anything and everything has been tested for problems or infection. He started to limp a little bit a while back and I immediately called it, he tore his ACL. He is a little overweight but no diabetes. Other than that, nothing medically wrong with him with infection, or with his organs. Just looking holistically for something to give him to see if it can make it not so hard on the grass.
