What is diabetes?

Diabetes mellitus is a condition that develops when your dog cannot use sugar (glucose) effectively and control their blood sugar levels. Insulin, which is made in the pancreas, is essential for regulating the use and storage of blood glucose. Insufficient insulin production is potentially life threatening.

Just like in humans, diabetes in dogs is serious, but manageable. There are two types of diabetes, and although there is no cure, dogs with either type can be successfully managed through nutrition, exercise and, if necessary, regular insulin medication. With the right food and advice from your veterinarian, your diabetic dog can still enjoy a happy, active life.

What causes diabetes?

A reduction in insulin production is usually caused by damage to the pancreas. The pancreas is responsible for producing the proper amount of insulin to control sugar levels. In some dogs, hormonal changes or medications can reduce the effect of insulin. If your dog's pancreas is damaged, long-term and potentially life-threatening symptoms could occur and must be managed.

Factors that increase the chance of your dog developing diabetes include:

Body condition. Overweight or obese dogs are more likely to develop diabetes.

Age. Dogs can develop diabetes at any age, but the peak onset is around eight years.

Gender. Females are twice as likely to develop diabetes.

Breed. Some breeds of dogs, such as Samoyeds, miniature schnauzers, miniature poodles and bichon frise, are more predisposed to diabetes than others.

Other factors could include poor nutrition, hormonal abnormalities and stress.

Does my dog have diabetes?

The signs of diabetes are difficult to recognise because they are similar to those of other disorders like kidney disease. The Animal Trust says that classic early signs of diabetes include:

  • Excessive thirst
  • Increased urination
  • Weight loss despite normal or increased appetite

As the disease advances, they note that you may see symptoms like:

  • Loss of appetite
  • Lack of energy
  • Lethargy
  • Vomiting
  • Vision difficulties and cataracts

Canine diabetesIf you notice any of these signs, please contact your veterinarian. They will likely need to perform tests to ensure an accurate diagnosis.

IMPORTANT: Once diabetes is diagnosed, it is important that your dog is regularly monitored. Your veterinarian will check your dog’s glucose levels and will adjust medication to keep your dog stable.

Treatment and the importance of nutrition

While there is no cure for diabetes mellitus, the PDSA reassures pet owners that canine diabetes can be controlled with insulin, exercise and proper nutrition.

Balanced nutrition is an essential part of diabetes management and overall health and wellbeing for your dog. When your dog has diabetes, it’s even more important to feed them the right dog food consistently. Feeding a veterinarian-recommended food with a consistent nutrient profile will help keep your dog's metabolism stable so they can stay healthy.

Fibre is particularly important in managing the disease because moderate to high-levels of fibre can lower insulin requirements and blood glucose levels. Fibre also makes the body more responsive to insulin.

Routine is key, so feeding, exercise and, if necessary, giving medication should take place at the same times each day. This helps maintain stable blood glucose levels. Your veterinarian and health care team will give you advice.
