hi, my 12 year old ginger was diagnosed with diabetes 2 mths ago. Vet prescribed vetsulin, twice a day. After several adjustments, we Hv found d dosage that works and his fructosamine test result today was in good range. However, over a period of a week he has lost abt half a kg. I was away this period but someone was taking care of him and he was eating well. Anyone has an idea why he suddenly lost weight when his diabetes is regulated?
