Diabetes in Dogs: Symptoms

The occurrence of diabetes in canines is increasing. Find out what it is and what symptoms to watch for.

What is Diabetes in Dogs?

Diabetes is an endocrine disorder. The endocrine system features glands that produce and discharge hormones which regulate many bodily functions.

Insulin is one of these hormones. Like the human body, a dog’s body needs insulin to properly regulate blood sugar levels and to respond correctly to normal insulin levels.

Diabetes can lead to high blood sugar (hyperglycaemia) which can cause various health problems if left untreated.

Types of Diabetes in Dogs

1. Diabetes Mellitus: Sugar Diabetes

   Type 1: The most common type associated with a lack of insulin production.

   Type 2: Inability to respond to insulin production and impaired insulin production. This type of diabetes is more common in humans.

2. Diabetes Insipidus: Water Diabetes

   Diabetes insipidus is a very rare condition associated with excessive urination because the body fails to properly control water balance. This condition is not related to blood sugar or insulin but is rather a problem with anti-diuretic hormone (ADH).
