What is diabetes?

There are two types of diabetes in dogs:

  • Diabetes insipidus. Sometimes also known as “drinking diabetes”, diabetes insipidus leads to the failure to regulate the body’s water content. It is extremely rare in dogs.
  • Diabetes mellitus. Diabetes mellitus, sometimes also known as “sugar diabetes” is much more common. It is caused by an insulin deficiency, either because the pancreas fails to produce enough insulin or because the body cannot adequately utilise insulin.

This article will focus on diabetes mellitus in dogs and its causes, symptoms and treatment. Although a complex disorder, diabetes can be carefully managed to ensure that the affected dog can still live a long and healthy life.

What are the symptoms of diabetes in dogs?

The following symptoms could indicate that your dog has diabetes mellitus:

  • Increased appetite
  • Weight loss
  • Excessive thirst
  • Excessive urination
The above are the four classical signs of diabetes, but there are several other signs and symptoms that may present in more advanced cases:
  • Sweet-smelling or fruity breath
  • Lethargy or a lack of energy
  • Depression
  • Dehydration
  • Loss of appetite
If you suspect that your dog may have diabetes, take him to the vet as soon as possible for a full check-up. If left untreated, the disease can have a severe impact on your dog’s overall health and cause:
  • Cataracts (eventually leading to blindness)
  • An enlarged liver
  • Urinary tract infections
  • Vomiting
  • Chronic skin conditions
  • Kidney failure

What causes diabetes in dogs?

Diabetes mellitus is a disease of the pancreas. Its exact cause is unknown, but there are several factors that may contribute to the development of the disease. These include:

  • Autoimmune disease
  • Genetic predisposition
  • Obesity
  • Chronic or repeated pancreatitis
  • Steroid medications
  • Cushing’s disease
  • Abnormal protein deposits in the pancreas
How exactly does dog diabetes occur? Think of it this way: just like your car needs fuel to run, body cells need a sugar called glucose. Glucose comes from carbohydrates in your dog’s diet, but to extract glucose from the blood your dog relies on a crucial hormone known as insulin. Insulin is produced in the pancreas by special cells called beta cells. Diabetes mellitus occurs when those beta cells fail to properly regulate blood sugar, resulting in abnormally high levels of glucose in the blood. There are two types of diabetes mellitus:
  • Type 1 or insulin dependent diabetes mellitus. The most common form of dog diabetes, Type 1 occurs when the dog’s immune system attacks and destroys the body’s beta cells.
  • Type 2 or non-insulin dependent diabetes mellitus. Type 2 diabetes occurs when the pancreas still produces insulin but the body’s cells fail to properly respond to the hormone.

Are any dogs prone to diabetes?

There are several factors that can contribute to the likelihood of a dog getting diabetes, including:

  • Breed. Diabetes can occur in any purebred or mixed-breed dog. However, studies have shown that certain breeds have a higher risk of developing the disease. Examples of these breeds include Miniature Poodles, Pugs, Dachshunds, Australian Terriers, Fox Terriers and Beagles.
  • Age. Diabetes can occur at any age but it most commonly occurs in middle-aged and older dogs. It is usually diagnosed in dogs five years of age or older.
  • Gender. Unspayed female dogs are twice as likely to get diabetes as male dogs.
  • Weight. Obesity can make cells resistant to insulin, so it’s important to make sure your pet stays at a healthy weight.
  • Diet. Feeding your dog a diet high in fat can contribute to pancreatitis, and chronic or repeated cases of this condition can severely damage the pancreas and cause diabetes.

How should I treat diabetes in my dog?

If you suspect that your dog has diabetes, your vet will ask for details of any symptoms and perform a thorough physical examination. Bloodwork and urinalysis will then be used to diagnose the disease. The treatment program for your dog will vary depending on how severe the symptoms are and whether or not your pooch has any other health issues. However, the main goal of treatment is to keep your pet’s blood sugar level as close to normal as possible. Diabetes treatment in dogs usually requires daily administration of insulin, as well as dietary changes, regular exercise and a stress-free lifestyle. If your dog is seriously ill when first diagnosed, s/he may need to be hospitalised for several days so that your vet can regulate their blood sugar and bring the disease under control. After the dog has been stabilised, your vet will work out the best treatment plan to allow you to manage their condition at home.

Does pet insurance cover diabetes?

Yes. The good news is that if you have a pet insurance policy that includes illness cover, you’ll be covered for eligible vet bills arising from your dog’s diabetes treatment. Cover for chronic conditions like diabetes can also be maintained throughout your pet’s life, provided of course that you renew your policy annually without any break in cover and you don’t change your level of cover after your pet reaches the policy’s upper age limit. However, pet insurance doesn’t cover pre-existing conditions, so if your dog already suffers from the disease when you buy a policy then the insurer won’t be able to provide any protection.
