As a backround, about two months ago my 9 year old American Eskimo was diagnosed as having Canin Disc Disease. I had brought him in because he would yelp when he got up from laying down. It seemed to me that the pain was coming from his side, and not his spine. But after Xrays the vet said it was Disc Disease. I'm not so sure that was right, which leads me to this.
When I woke up this morning he had went diarrhea in the house. It was very dark in color, almost black. He did it again a few hours later. He also has uncontrolled urination as of today. A couple months ago, right after the diagnosis of Disc Disease, I started him on a raw diet of mainly deer meat and select fruits and vegetables. I did some research on uncontrolled urination and it seems that he may have kidney problems or even diabetes? Does that sound right? Is there any treatment you could think of for him?
Thanks
P.S. I forgot to add that when I switched him over to the raw diet that he lost 10lbs. I wonder if that was a result of his new diet or a symptom of whatever is causing the diarrhea/urination?
