Symptoms of Diabetes in Dogs – The Complete Guide

Our canine companions are not just pets; they’re part of the family. As pet owners, we strive to keep them healthy and happy. However, sometimes they can face health challenges that are beyond our control. One of these is diabetes, a condition that is not only common among humans but also dogs.

The symptoms of diabetes in dogs often include frequent urination, increased thirst, unexplained weight loss despite an increased appetite, lethargy, weakness, cloudy eyes or cataracts, and recurring infections, particularly urinary tract infections. Regular veterinary checkups are crucial for early detection.

This article aims to delve into the Symptoms of Diabetes in Dogs and provide you with a deeper understanding to help you keep your furry friend in good health.

5 Common Symptoms of Diabetes in Dogs

How to Deal With Diabetes in Dogs

Diabetes in dogs typically manifests as Diabetes Mellitus, which is characterized by a lack of insulin production in the dog’s body.

Without adequate insulin, your dog’s body can’t effectively regulate blood sugar levels, leading to hyperglycemia, or high blood sugar.

This condition can have dire effects if left untreated. But what are the symptoms of diabetes in dogs, and how can we spot them?

Frequent Urination and Increased Thirst

One of the first signs of diabetes in dogs is an increase in water consumption and consequently, urination.

If your dog is always at the water bowl or having “accidents” around the house, it might be a sign of high blood sugar levels, which the body tries to mitigate by flushing out through increased urination.

Weight Loss Despite Increased Appetite

You might notice that your dog is eating more than usual but is inexplicably losing weight.

This paradoxical symptom occurs because the body is not able to utilize glucose properly, leading to the burning of fat and muscle tissue for energy.

Lethargy and Weakness

Does your dog seem less playful than usual?

Dogs with diabetes often experience fatigue, lack of energy, and overall weakness, mainly due to the body’s inability to efficiently convert food into energy.

Cloudy Eyes or Cataracts

In some cases, dogs with diabetes may develop cataracts, or cloudy spots on their eyes. This can eventually lead to vision loss if left untreated.

If you notice your dog bumping into furniture or being hesitant to jump or climb, it could be a sign of impaired vision due to diabetes.

Recurring Infections

A lesser-known symptom of diabetes in dogs is recurring infections, particularly urinary tract infections (UTIs).

Diabetes can suppress the immune system, making your dog more susceptible to various infections.

Understanding the Risk Factors for Diabetes in Dogs

Certain factors can predispose your dog to develop diabetes.

Being aware of these can help you take preventive measures or detect the onset of the condition early.

Age, Breed, and Gender

Like humans, older dogs are more prone to developing diabetes.

Certain breeds, such as Samoyeds, Miniature Schnauzers, and Poodles, have a higher incidence rate. Female dogs, especially those unspayed, also face a higher risk due to hormonal fluctuations.


Excess body weight significantly increases the risk of diabetes in dogs, as it does in humans.

This is because obesity can lead to insulin resistance, where the body’s cells don’t respond effectively to insulin.


Pancreatitis, or inflammation of the pancreas, can lead to damage to the insulin-producing cells, increasing the risk of diabetes.

Autoimmune Disorders

Dogs with autoimmune disorders can also be at higher risk. In these conditions, the dog’s immune system mistakenly attacks its own body’s cells, potentially leading to damage to the pancreas and subsequent diabetes.


Certain medications, especially steroid drugs, can increase the risk of diabetes in dogs. They can interfere with insulin production and affect the body’s ability to regulate blood sugar levels.

Genetic Predisposition

Some dogs may be genetically predisposed to develop diabetes, just like some humans. If diabetes runs in your dog’s bloodline, it might be at a higher risk.

How to Deal With Diabetes in Dogs

Diabetes is a serious condition, but with proper management, your dog can still lead a happy and fulfilling life.

Insulin Therapy

Most diabetic dogs require daily insulin injections to control their blood sugar levels. Your vet can teach you how to administer these injections at home.

Dietary Modifications

Your vet will likely recommend a high-fiber, low-fat diet to help regulate your dog’s blood sugar levels and maintain a healthy weight.

Regular Exercise

Regular exercise can significantly help manage your dog’s blood sugar levels.

However, the exercise routine should be consistent, as sudden changes can affect blood sugar levels.

Regular Veterinary Checkups

It’s important to have regular check-ups with your veterinarian to monitor your dog’s condition and adjust the treatment plan if needed.

Regular blood tests can help keep track of your dog’s glucose levels and ensure they’re in the optimal range.

Home Blood Glucose Monitoring

Just like in humans, home blood glucose monitoring can be a valuable tool in managing diabetes in dogs.

Your vet can show you how to use a home glucose monitor to keep track of your dog’s blood sugar levels.

Management of Underlying Conditions

If your dog has other conditions, like obesity or pancreatitis, managing these can also be crucial in controlling their diabetes.

This might include additional dietary changes, medication, or even surgery in some cases.

Frequently Asked Questions (FAQs)

1. Can diabetes in dogs be cured?
