Dog Diabetes: Symptoms, Causes, and Care Guide

Sep 14, 2025

Diabetes is a complicated condition that primarily affects elderly dogs. Dogs with diabetes may experience a variety of unpleasant symptoms, much like people. Their quality of life need not be impacted by this condition, though, provided it is managed carefully.

 

What is diabetes in dogs?

Dog diabetes, also known as "canine diabetes," is brought on by either your dog's body not producing enough insulin or, in certain situations, a biological reaction that is "inadequate." The food is broken down as your dog consumes. Insulin transports glucose, one of the ingredients in their diet, to their cells.

The glucose cannot be used correctly if your dog is unable to make enough insulin on their own or if they are not using the insulin they do have appropriately. This implies that your dog's blood sugar levels will increase, perhaps resulting in negative side effects.

 

What causes diabetes in dogs?

The exact cause of diabetes in dogs is unknown, much like in people. It's possible that certain dogs are more genetically predisposed to the illness. However, it is well recognised that your dog's chance of acquiring diabetes is increased if they are overweight. This might be as a result of your dog's bodily cells becoming more insulin-resistant due to obesity.

The most likely time for your dog to have diabetes is when they begin to age. Additionally, neutered dogs and female canines could be more vulnerable.

What are the symptoms of diabetes in dogs?

Dogs with diabetes can exhibit a wide range of symptoms. Ask your veterinarian for guidance if you observe any of the following, since these may be signs of the condition:

  • Too much thirst
  • Urination has increased.
  • Changes in appetite
  • "Delicious-smelling" breath
  • Fatigue or a lack of vitality
  • infection of the urinary tract
  • Blindness

Your veterinarian will probably do a blood test to aid in the diagnosis if they feel your dog may have diabetes. They can advise you on the best course of action if your dog has diabetes.

 

Is there a cure for dog diabetes?

Regretfully, diabetes in dogs cannot be cured.  On the other hand, diabetes in dogs is a disease that the owner can often treat.  Your dog can still lead a full and contented life if they are properly cared for.

 

How can I manage dog diabetes?

Maintaining your dog's blood sugar levels at a "normal" level is the goal of managing diabetes in dogs. Your veterinarian can assist you with this and provide a continuous treatment plan for your dog. Continuing care typically entails:

  • Taking insulin on a regular basis (up to twice a day)
  • Keeping an eye out for any changes in your dog's symptoms
  • Frequent visits to the veterinarian
  • A dog meal made especially for diabetic dogs could help certain canines.

 

How can I help prevent my dog developing diabetes?

There is no way to ensure that your dog won't have diabetes. But you can lower the risk by making sure your dog has a healthy lifestyle. Among the advice for leading a healthy lifestyle are:

  • Supplying children with a healthy, balanced diet
  • Assisting them in maintaining a healthy body, such as not being overweight
  • Getting adequate exercise in relation to their age and diet

 

Other conditions to watch out for

Because diabetic dogs are more likely to develop other diseases, it's critical to monitor them for any odd symptoms. Dogs with diabetes are more likely to:

  • Cataracts:- they can form when the eyes are affected by high blood sugar levels. Although many dogs do well with less vision since their sense of smell and hearing is so much superior to ours, cataracts can be surgically corrected.
  • Urinary tract infections:- Your dog is more likely to have these if there is too much sugar in their urine. Ask your veterinarian for guidance if you notice more urination or pain during urinating.
