Our Jake is 11yrs old. His lab work shows an elevated ALT and low blood sugar. He is going to have some more tests this week. He had been on a very low dose of Rimadyl and the vet took him off for a month. The results came back the same. Some of the worst diagnoses could be liver problems, Addison’s, and also an insulinoma of the pancreas. I am at a loss. Has anyone else had these problems with their dogs???
