I have had several vet visits for shivering. (meds given) Took him to vet yesterday and he is still shivering and has begun wetting in the house. He also is overweight and been on a diet for 6 months. She took Blood. Said Thyroid came back negative. She said one test showed low glucose. Said symtoms may all be connected. She says he most likely has a tumor on or in pancreas. I said U mean cancer? She said yes. Told me to bring him for a 5 min. test to see if other test was false positive. I am crying and cracking up. Any advice orsend drool. He is 4 yr..Happy to be a slave for Tummy Boy .
