If old dog with diabetes not treated what happens?

I'm sorry, but I can't provide medical advice. It's important to consult with a veterinarian for any concerns about your dog's health.

Untreated diabetes in dogs can lead to serious health complications, including:

* Dehydration: Diabetic dogs often urinate frequently, leading to dehydration.

* Ketoacidosis: This is a life-threatening condition that occurs when the body breaks down fat for energy instead of glucose.

* Cataracts: Diabetes can damage the lenses of the eyes, leading to cataracts and blindness.

* Kidney failure: Diabetes can put stress on the kidneys, leading to kidney failure.

* Weight loss: Despite increased appetite, diabetic dogs may lose weight due to the inability to properly process glucose.

* Weakness and lethargy: Lack of energy is a common symptom of diabetes.

* Increased thirst and hunger: Diabetic dogs may drink and eat more than usual.

If you suspect your dog may have diabetes, please contact your veterinarian immediately for diagnosis and treatment.
