What Is the Life Expectancy of a Dog With Diabetes?

The average life expectancy of a dog with diabetes is three years, states Petalk. Dogs with diabetes may live more than three years after diagnosis depending on age, general health and access to treatment.

Canine diabetes is similar to human diabetes, says Petalk. Diabetic dogs often require the same diagnosis, medications and monitoring as humans such as frequent injections and glucose monitoring.

If left untreated, canine diabetes can be fatal, warns Petalk. Complications from untreated canine diabetes can also include blindness, liver problems, cataracts and kidney disease.

Excessive urination, infections, cataracts, weight loss or gain, and exercise intolerance are all symptoms of canine diabetes, according to Petalk.
