Poor Larry! It sounds like it’s time to move onto further diagnostics. Obviously something is wrong and it just hasn’t been discovered yet. I recommend to discuss an abdominal ultrasound with your veterinarian and possibly checking a fructosamine level to see if the blood sugars have been elevated over the past month. This will help to figure out if diabetes, pancreatitis, cancer or inflammatory bowel disease is present. I hope this gets figured out quickly. Best of luck and please feel free to post any additional questions.
