How Long Do Dogs Live with Type 2 Diabetes?


The health and wellbeing of our dogs is a concern shared by all dog owners. An essential part of caring for our pets involves understanding the health issues they may face.

One condition that has seen a rising prevalence in dogs is diabetes, specifically type 2 diabetes. This article explores the life expectancy of dogs living with type 2 diabetes, providing an in-depth look at the complexities of this disease.

Type 2 diabetes in dogs, much like in humans, is a chronic condition that impacts the body’s ability to regulate blood glucose levels. This inability results in an excess of sugar in the bloodstream, which, over time, can lead to serious health complications.

Understanding the life expectancy of dogs diagnosed with this condition, as well as the factors that contribute to it, is vital for every pet owner.

In this article, we provide detailed information about type 2 diabetes in dogs, from understanding the disease to its symptoms, treatment options, and management strategies. Additionally, we will delve into how this disease can impact a dog’s life expectancy and how early diagnosis and proper treatment can contribute significantly to improving their quality of life.

How Long Do Dogs Live with Type 2 Diabetes?

Dogs with type 2 diabetes typically have a median survival time of around two years, but this can extend with appropriate treatment and care. Factors like age, disease severity, and timing of diagnosis can affect the lifespan. With appropriate treatment and regular checks-ups, diabetic dogs can also live a full and happy life free of symptoms.

Understanding Diabetes in Dogs

What is Canine Diabetes?

Canine diabetes is a chronic illness that affects a dog’s ability to regulate blood glucose levels. This metabolic disorder occurs when a dog’s body cannot produce sufficient insulin or cannot use insulin effectively, leading to elevated glucose levels in the blood.

Types of Diabetes in Dogs

There are two primary types of diabetes that can affect dogs:

  1. Type 1 Diabetes: This is the most common form of diabetes in dogs, where the body’s immune system destroys the insulin-producing cells in the pancreas. Dogs with this type need daily injections of insulin to maintain normal blood sugar levels.
  2. Type 2 Diabetes: Less common in dogs, this type occurs when the body becomes resistant to the effects of insulin or when there is a relative insulin deficiency. Obesity is often a contributing factor in this type of diabetes.

Type 2 Diabetes in Dogs

In dogs, type 2 diabetes is not as prevalent as type 1. It usually occurs in older, overweight dogs. Unlike type 1, it is often associated with insulin resistance rather than an outright lack of insulin. With proper diet and exercise, along with appropriate medication, dogs with type 2 diabetes can effectively manage their blood glucose levels and lead a full, happy life.

Recognizing the Symptoms of Type 2 Diabetes in Dogs

Common Signs of Diabetes

If your dog has developed type 2 diabetes, they may exhibit a range of symptoms, some of which can often go unnoticed initially. However, early detection is crucial to ensure effective management of the disease. Key signs of canine diabetes include but are not limited to excessive thirst, frequent urination, unexplained weight loss despite increased appetite, fatigue and lethargy, fruity smelling breath and frequent urinary tract infections.

While the above are the common signs, there are other symtoms which may not appear immediately on the onset of diabetes. For a detailed understanding, check out our article on the various signs of diabetes in dogs.

Life Expectancy of Dogs with Type 2 Diabetes

General Life Expectancy

The lifespan of dogs diagnosed with type 2 diabetes can significantly vary. However, with appropriate intervention and management, many diabetic dogs can continue to lead a full and contented life.

The median survival time post-diagnosis is approximately two years, but it’s not uncommon for dogs to live well beyond this timeframe.

Dr. Behrend’s Findings

Studies led by Dr. Ellen Behrend, an esteemed veterinary specialist in endocrinology, indicate that the survival rates of dogs with diabetes have been steadily improving over the years. This improvement is credited to advancements in insulin therapy and better management of the disease.

Variables that Can Affect Life Expectancy

Several variables can influence the life expectancy of a dog diagnosed with diabetes. These factors include:

  • Age at diagnosis: Younger dogs generally have a better prognosis.
  • Severity of the disease: Dogs with milder forms of the disease typically have a better survival rate.
  • Early diagnosis: Catching the disease early can significantly improve prognosis.
  • Effective management: Consistent insulin therapy, regular vet checkups, and a suitable diet can increase longevity.

Importance of Early Diagnosis

The key to managing diabetes and improving your dog’s life expectancy lies in early diagnosis. Symptoms of diabetes may be subtle initially but catching the disease early can help start treatment promptly.

Early intervention can reduce the risk of complications, ensuring your dog maintains a high quality of life. Remember, diabetes is a manageable disease, and your dog can live a happy, fulfilling life with proper treatment and care.

Complications of Type 2 Diabetes in Dogs

Diabetic Ketoacidosis (DKA)

Diabetic Ketoacidosis (DKA) is a life-threatening complication that can occur in dogs with poorly regulated diabetes. It occurs when the body cannot utilize glucose due to insufficient insulin, causing it to break down fat for energy instead. This process leads to an accumulation of ketone bodies, which make the blood acidic.

Symptoms of DKA include excessive thirst, frequent urination, nausea and vomiting, abdominal pain, weakness, rapid breathing or panting, a fruity smelling breath, and confusion. If you notice these symptoms in your dog, seek immediate veterinary care.

Other Potential Complications

  1. Urinary Tract Infections (UTI): Dogs with diabetes are more susceptible to UTIs due to the excess sugar present in their urine, which provides a fertile breeding ground for bacteria.
  2. Kidney Failure: Prolonged high blood sugar levels can damage the kidneys, potentially leading to kidney failure, a serious condition that requires urgent veterinary attention.
  3. Blindness: Over time, uncontrolled diabetes can lead to cataracts, causing cloudiness in the lens of the eye and eventually blindness.

While these complications can be daunting, it is essential to remember that they are preventable. Regular veterinary checkups, proper management of blood sugar levels, and a healthy lifestyle can significantly reduce the risk of these complications. Your vet will guide you through this process, providing the best care for your dog.

Is Strawberry Yogurt Safe for Dogs with Type 2 Diabetes?

Strawberry yogurt can be a tasty treat for dogs with Type 2 diabetes. However, it is important to choose a dog-friendly strawberry yogurt without added sugars or artificial sweeteners. Always consult your vet before introducing any new food to your dog’s diet to ensure it is safe for their specific condition.


In conclusion, a diagnosis of Type 2 diabetes in your dog is not a death sentence. Indeed, it does require effort, dedication, and an unwavering commitment to managing the disease effectively.

While the life expectancy of a diabetic dog can vary, with appropriate and timely intervention, many dogs with this condition can live a full, happy life for many years.

Key to managing this disease is early detection, which hinges on the dog owners’ understanding of the symptoms. Regular vet check-ups, appropriate insulin therapy, and lifestyle modifications like diet control and regular exercise significantly contribute to managing the disease and its complications.

End-of-life decisions are inevitably tough, filled with guilt and regret. But remember, as a pet parent, your primary goal is to ensure your pet’s quality of life.

Support from professional counselors or pet support groups can be invaluable during such periods.
