Warning Signs of Dog Diabetes and Cat Diabetes: 3 Key Symptoms to Watch for - Overeating, Drinking, and Frequent Urination

This article was written by Dr. Shang-Hsiu Chung, a veterinarian at Always Care Veterinary Hospital

Dog and cat diabetes is on the rise each year, posing a growing health risk that owners must be vigilant about. Key symptoms include overeating in dogs and cats, polydipsia in dogs and cats, increased thirst and urination in dogs and cats, and unexpected weight loss. Obesity in pets further raises the risk. Understanding these risk factors early allows for timely detection and treatment.
 

Why Do Dogs and Cats Develop Diabetes? How Do Veterinarians Diagnose It?


Diabetes in dogs and cats is an endocrine disorder that prevents cells from properly absorbing glucose, causing elevated blood sugar and increased osmotic pressure.  This results in symptoms like excessive urination and glucose in the urine. Normal blood sugar levels for pets range from 70-150 mg/dL; levels exceeding 300 mg/dL suggest diabetes, requiring insulin treatment to manage the condition.
So, what causes the body to fail in absorbing glucose from the blood? The main issue lies in insulin's inability to work properly, which can occur in one of two ways:

  1. Insufficient insulin secretion (more common in dogs): This is classified as Type I diabetes, requiring insulin injections to manage glucose levels.
  2. Impaired insulin receptors (more common in cats): This is known as Type II diabetes and can often be managed or reversed with dietary changes and appropriate treatment.


Who are the high-risk groups for diabetes in dogs and cats?

 
  1. Breeds at higher risk: Due to genetic factors, some dog and cat breeds are more susceptible to obesity or hormonal imbalances, raising their risk of diabetes.

  2. Obesity: Can lead to insulin dysfunction and impair the ability to maintain normal glucose levels.
  3. Inflammation: Inflammatory reactions release substances that interfere with insulin's normal operation.
  4. Long-term medications: steroids, progesterone or immunosuppressants, etc.
  5. Existing conditions: kidney disease, pancreatitis, periodontal disease, thyroid disorders, adrenal hyperactivity, and others.
  6. Pregnancy in cats: Hormonal fluctuations can impact insulin operation.


What symptoms does diabetes cause in dogs and cats?

 
  1. Overeating, excessive drinking, and increased urination: When glucose isn't effectively absorbed, the pet feels hungrier and eats more. High blood sugar raises osmotic pressure, causing the pet to urinate more, which in turn increases thirst and water intake.
  2. Weight loss: Due to elevated metabolism and ineffective glucose absorption, the pet experiences weight loss.
  3. Dehydration: Signs may include a lack of elasticity and luster in the coat. Evaluation can be done by observing the skin's rebound time, gum color and dryness, and whether the eyes are sunken.
  4. Cataracts in dogs: High blood sugar levels can alter the structure of lens proteins, leading to cataracts.
  5. The cat walking on its heels: Chronic high blood sugar may damage peripheral nerves, causing weakness in the limbs.


Tips for Preventing Diabetes in Cats and Dogs


  1. Diet modification to stabilize glucose: A high-protein, low-carbohydrate diet is recommended to help maintain stable glucose levels.
  2. Enhance metabolism and manage weight: Increasing metabolism helps pets maintain an ideal weight. Dietary supplements like probiotics, which stimulate fat metabolism, are recommended.

  3. Support joint health and enhance mobility: Joint wear and tear can reduce your pet's mobility, potentially leading to obesity. Supplementing with probiotics can help nourish joints and improve mobility.
  4. Gut health for stronger immunity: The gut plays a crucial role in the immune system. A healthy gut microbiota boosts immunity, helps balance metabolism, and supports weight management in your pet.

Diabetes in dogs and cats is a significant health concern for pet owners. If your pet has diabetes, regular check-ups are essential to keep them in optimal health.

Is Pet Fish Oil Worth It? Understanding Omega-3 Benefits, Selection Tips, and Safe Supplementation

In recent years, more and more pet owners have started supplementing their dogs’ and cats’ diets with fish oil. Whether it is for skin allergies, excessive shedding, joint degeneration, or cardiovascular support for senior pets, fish oil has become one of the most popular nutritional supplements available today. However, many pet owners do not realize that the true value of fish oil lies not in the oil itself, but in the Omega-3 fatty acids it provides. EPA and DHA are the key nutrients responsible for most of the health benefits associated with fish oil supplementation.

How to Improve Bad Breath in Cats and Dogs? A Veterinarian’s Guide to Oral Care and Whole-Body Health

Is bad breath in cats and dogs just a sign of aging or simply the result of food? Occasional odor may not be a concern. However, persistent or worsening bad breath should not be ignored. In many cases, it is associated with plaque buildup, gum inflammation, or periodontal disease—early warning signs that pet owners often overlook. As oral bacteria accumulate over time, they not only intensify the odor but can also cause discomfort or pain. Clinically, pets may show signs such as reduced appetite, reluctance to eat dry food, slower eating, or even dropping food while chewing. At this stage, bad breath is no longer just a “smell issue”—it’s a signal that oral health needs attention.
