Canine Insulinoma is a disease of old dogs which results from a functional neoplasm involving the beta cells of the islets of Langherhans of the pancreas. These are the same cells that are involved in diabetes mellitus where insulin production is decreased instead of increased. The insulinoma dog is usually admitted with signs of weakness, ataxia, restlessness, ravenous appetite, and convulsions.
