Post #19: Diabetes in dogs

Did you know that your beloved family pet is susceptible to diabetes? Just as in humans, canine diabetes is a potentially life-threatening disease when left uncontrolled. There are two different types that dogs are susceptible to – diabetes insipidus and diabetes mellitus.

Diabetes insipidus is a metabolic disorder, where the body is not able to produce the anti-diuretic hormone vasopressin, responsible for controlling the kidney’s intake of water. Signs of diabetes insipidus include excessive thirst and urination, disorientation and seizures.

Diabetes mellitus is a chronic endocrine disease, and is the most common type of diabetes found in dogs. It is characterized by the inability to produce any or enough insulin to sustain the body, resulting in high blood sugar. Symptoms of diabetes mellitus include fatigue, excessive thirst and urination, weight loss, increased appetite and cataracts.



Dogs that are overweight or obese are at a significantly increased risk of developing diabetes mellitus. Just as in human diabetes, their diet plays an incredibly important role in proper management.


Along with insulin therapy and exercise, your veterinarian will advise following a strict diet plan. This plan will vary depending on the particular dog, but most likely will be high in fiber, as fiber-rich food aids in digesting and absorbing carbohydrates, which can reduce blood glucose levels.

If you notice any of the following symptoms in your dog, please visit your local trusted veterinarian immediately:

  • Excessive thirst and urination
  • Fatigue
  • Rapid weight loss
  • Disorientation
  • Cataracts
