    Diabetes in Dogs

    Diabetes Mellitus in dogs occurs when the body lacks insulin (Type I) or the cells respond incorrectly to insulin (Type II). Insulin, released by the pancreas during digestion, helps convert glucose into energy.


    Causes of Diabetes in Dogs

    Genetics: Breeds like Beagles, Poodles, and Dachshunds are more susceptible. Medical Conditions: Cushing’s disease, pancreatitis, and obesity can contribute.

    Symptoms of Diabetes in Dogs

    Early signs include excessive thirst, increased urination, and weight loss despite a normal appetite. Advanced symptoms may lead to sudden blindness, loss of appetite, lethargy, and vomiting.

    Treatment and Monitoring

    Diet: High-quality protein, fiber, and complex carbohydrates help manage glucose levels. Prescription diets or alternatives like Chappie can be considered. Exercise: Consistent, moderate exercise prevents glucose level fluctuations. Injections: Most dogs require daily insulin injections. Administered at the same time each day, varied. injection sites reduce discomfort. Avoid ‘piggybacking’ doses to prevent low blood glucose. Monitoring: Regular vet checks and monitoring clinical signs, blood glucose, and urine glucose levels. Blood glucose curve, fructosamine, and general health profile tests provide insights.

    Complications and Life Expectancy

    Complications: Adjustments take time, and some dogs may not respond as expected due to underlying health problems, insulin issues, or duration of insulin effect. Life Expectancy: Well-managed diabetes allows dogs to live a good quality of life. Regular treatment and monitoring are essential.


    Contact the vet immediately for ketoacidosis (lethargy, vomiting) or hypoglycemia (confusion, weakness). Apply glucose gel if conscious. If concerned about diabetes signs in your pet, contact your local Animal Trust surgery promptly.
