Diabetes in pets or diabetes mellitus is a common endocrine disorder found in pets, particularly dogs and cats. This condition occurs when the body is unable to properly regulate blood glucose levels, leading to high blood sugar. It’s extremely crucial to understand the signs and symptoms of diabetes in your furry friend for early diagnosis and effective management.

What is Diabetes in Pets?

Diabetes in pets can manifest in two primary forms: Type 1 diabetes, where the body does not produce enough insulin, and Type 2 diabetes, where the body’s cells become resistant to insulin. Although less common, Type 1 is more frequently seen in dogs, while Type 2 is prevalent in cats, especially for those who are overweight or older.

Signs and Symptoms

As pet owners we should be extra vigilant for the following signs of diabetes:

  1. Increased Thirst and Urination: One of the hallmark signs of diabetes is polydipsia (or increased thirst) and polyuria (increased urination). You may notice your furry friend drinking more water and needing to go outside or use the litter box more frequently than they used to.
  2. Increased Hunger: Despite eating more, diabetic pets often experience weight loss. This can be puzzling, as they may appear to be constantly hungry.
  3. Lethargy: Pets with diabetes may become lethargic and less active. If your pet seems unusually weak or tired, it may be a sign of elevated blood sugar levels.
  4. Poor Coat Condition: Diabetes in pets can lead to skin and coat issues, such as a dull appearance or even hair loss.
  5. Unusual Breathing: In severe cases, pets may develop diabetic ketoacidosis (DKA), a life-threatening condition resulting from the body breaking down fat for energy instead of glucose. This can cause rapid, labored breathing and a sweet or fruity odor on the breath.

Diabetic Ketoacidosis (DKA)

DKA occurs when insulin levels are insufficient, and the body begins to break down fat for energy, producing ketones as a byproduct. If your pet shows signs of DKA, such as extreme lethargy, vomiting, dehydration, or unusual breathing patterns, seek veterinary care immediately. This condition requires urgent treatment and can lead to severe complications if not addressed promptly.

Managing Diabetes in Pets

If your pet is diagnosed with diabetes, management is essential for maintaining their quality of life. Regular veterinary check-ups, a consistent diet and insulin therapy are key components. Here are some important considerations:

  1. Never Give Insulin Without Checking Blood Glucose: If your pet is acting sick, weak, or refusing to eat, it is crucial to check their blood glucose (BG) levels before administering insulin. Giving insulin when BG levels are low can lead to dangerous hypoglycemia, which can be life-threatening.
  2. Bring Insulin and Syringes to the Vet: If you need to take your pet to the veterinarian, always bring their insulin and syringes. This allows the veterinarian to confirm the type of insulin and the dosage you have been administering, ensuring they can provide appropriate care and adjustments if necessary.


Diabetes in pets can be a challenging condition, but with proper understanding and management, pets can lead happy, healthy lives. If you notice any signs of diabetes in your pet, consult your veterinarian for a thorough examination and diagnosis. Early detection and consistent care are vital in managing diabetes and preventing complications such as DKA. By staying informed and vigilant, you can ensure your furry companion receives the best possible care.
