Diabetes In Pets

Diabetes in pets is becoming increasingly common, affecting both cats and dogs of various breeds and ages. Much like in humans, diabetes in pets occurs when the body cannot properly use or produce insulin, leading to elevated blood sugar levels. Symptoms include increased thirst, frequent urination, weight loss despite regular eating, lethargy, and, in advanced cases, blindness or serious infections. Early detection significantly improves treatment outcomes, allowing pets to lead comfortable, active lives. Management typically involves dietary changes, regular exercise, and consistent insulin therapy, tailored specifically to each pet’s individual needs. Owners who understand diabetes in pets and monitor their animal closely can help reduce the risk of complications and enhance their pet’s quality of life. By staying informed about this condition, pet parents can recognize warning signs early and collaborate effectively with veterinarians to ensure long-term health and well-being for their furry companions.

Did you know that over one percent of our canine companions develop diabetes at some time in their lives? Diabetes is not as frequent in pets as it is in humans, but it is not unknown. In this piece, a local Fort Myers, FL vet discusses some basic diabetic information for pets.

What is Diabetes Mellitus?

Diabetes affects both humans and animals in very identical ways. It is a condition that occurs when the pet’s body is unable to digest glucose, which is required to fuel the body. Insulin has a role here. Insulin regulates the process of converting glucose into fuel. To put it another way, insulin governs the physiological process that converts Fido’s favorite canine treat into a round of zoomies and happy dancing. When that procedure fails, it has a negative impact on your pet’s body.

Diabetes has two variations. In Type 1, insulin-deficiency diabetes, the body does not manufacture insulin. If a pet develops this type of diabetes, they will need insulin shots every day. Type 2 diabetes is distinguished by the body’s inability to adequately utilize insulin. In rare circumstances, the puppy’s pancreas generates insulin, but it is either insufficient or the dog’s cells are unable to effectively digest it. This is more common in overweight dogs and/or those in their elderly years. It’s also the most prevalent type in cats. 

Regardless of what the pet has eaten, both forms eventually cause the body to starve for energy. The illness also causes sugar to accumulate in the blood, despite the fact that the cells require glucose. The body will then begin metabolizing fat and protein. That can be pretty hazardous. Elevated glucose levels are likewise harmful and can cause serious organ damage.

What Are Some Warning Signs of Diabetes in Pets?

It’s always a good idea to keep an eye on your pet and look for symptoms that something is wrong. Diabetes can be managed much better with early intervention.

Here’s what to look for:

• Increased Thirst
• Increased Urine output 
• Weight loss 
• Increased Appetite 
• Lethargy
• Weakness
• Cloudy vision
• Unusual Stride
• Dull Fur
• Skin infection
• Urinary Tract Infections

If you notice any of these, contact your veterinarian immediately. 

How Do I Look After My Diabetic Pet?

Fido and Fluffy will most likely need diabetic therapy for the rest of their lives. There is no reason to panic, however. Caring for a diabetic pet may not be very different than caring for any other pet. In certain situations, the condition can even be reversed, however no promises are provided.

After a comprehensive evaluation of your pet, your vet will be able to provide particular treatment alternatives. 

Diet: Your pet’s diet is the foundation of their overall health. You should provide your dog or cat with a high-quality brand that has few carbs. Portion management is also vital. Even giving your dog a few extra calories each day can result in weight gain.

Glucose Monitoring: You must also test your pet’s blood, urine, or both on a regular basis to determine their glucose levels. This is quite easy once you are used to it.

Insulin: Insulin injections may appear scary at first, but they are actually very straightforward. Once you and your pet are accustomed to the procedure, it will most likely just take a few minutes each day.

Medication: Certain drugs can also help regulate blood sugar levels.

Veterinary Care: Pets with diabetes may need to come in more frequently, especially if they have additional problems. Keep up with those veterinary appointments.

Knowing Symptoms to Watch Out For: Watch for symptoms of hypoglycemia and/or diabetic ketoacidosis. These include weakness, lethargy, tremors, seizures, uncoordinated motions or unusual walking, sweet-smelling breath, acting more quiet than usual, unwillingness to eat or drink, vomiting, diarrhea, quick/erratic breathing, cataracts, high blood pressure, and urinary tract infections. Call your Fort Myers, FL vet if you notice any of these.

What Are Diabetes’ Health Risks?

Diabetes in pets can lead to a variety of secondary health issues, some of which are potentially fatal. Cataracts, liver and kidney disorders, and seizures are a few of them.

Then there’s ketoacidosis, which is very dangerous. When the body is starving for fuel—regardless of how much glucose is in the blood—it begins to break down fat and proteins. This leads to the production of ketones. While modest levels of ketone bodies in the blood are considered acceptable, high levels wreak havoc in the body. They make the blood more acidic, disrupting the electrolyte equilibrium. As a result, the body becomes dehydrated. This may be followed by brain cell enlargement, organ failure, and impaired muscle function. Ketoacidosis can be fatal if not treated, so it is definitely something to be taken seriously.

2025 Treatment and Management of Diabetes in Pets

What is the difference in treatment approaches between dogs and cats?

Treatment approaches for diabetic dogs and cats differ notably due to how diabetes typically manifests in each species. Dogs usually develop insulin-deficiency diabetes (Type 1), requiring daily insulin injections as their bodies produce little to no insulin naturally. Conversely, cats often have Type 2 diabetes, characterized by insulin resistance, frequently linked to obesity. Therefore, feline treatment strongly emphasizes weight management through a low-carbohydrate diet, portion control, and medications aimed at improving insulin sensitivity. Dogs also benefit from controlled diets, but daily insulin injections remain fundamental. Regular glucose monitoring and veterinary check-ups are recommended for both species.

What are remission rates and factors affecting them?

Remission in diabetic pets, particularly cats, refers to the period when insulin therapy is no longer needed due to normalized blood glucose levels. Cats have higher remission rates than dogs, often reaching up to 40–60% with appropriate treatment. Factors affecting remission include early detection, proper dietary management (especially low-carbohydrate diets), weight reduction in overweight pets, and consistent glucose monitoring. Conversely, older age, prolonged uncontrolled diabetes, and concurrent illnesses reduce remission likelihood. Regular veterinary visits and strict adherence to therapeutic regimens significantly improve remission rates and contribute to overall pet health.

What is the role of glucagon in diabetes?

Glucagon plays an opposite role to insulin, acting to raise blood sugar levels. When blood glucose drops too low, glucagon signals the liver to release stored glucose, stabilizing energy levels. In diabetic pets, particularly when insulin regulation is disrupted, glucagon can exacerbate hyperglycemia by continuing to prompt glucose release despite already elevated blood sugar levels. This imbalance worsens diabetic complications and increases the risk of ketoacidosis. Effective diabetes management in pets involves monitoring both insulin and glucagon activities to maintain proper glucose regulation, preventing dangerous fluctuations in blood sugar.

How do hormonal changes affect diabetes in intact female dogs?

Hormonal changes in intact female dogs significantly influence diabetes management, particularly due to fluctuations associated with heat cycles. During estrus, progesterone increases dramatically, leading to insulin resistance by interfering with insulin receptors and glucose utilization. Consequently, blood sugar levels may spike, complicating diabetic control. Elevated progesterone can trigger severe hyperglycemia, increasing the risk of ketoacidosis and other diabetes-related complications. Spaying eliminates these hormonal fluctuations, enhancing blood glucose regulation and overall stability. Therefore, managing diabetes in intact females typically requires more frequent veterinary monitoring, careful glucose management, and consideration of spaying to achieve optimal diabetes control.

What is diabetic ketoacidosis (DKA) and how is it treated?

Diabetic ketoacidosis (DKA) is a severe complication of diabetes occurring when a pet’s body, unable to utilize glucose properly, starts breaking down fats and proteins instead. This breakdown creates ketones, causing the blood to become dangerously acidic, disrupting electrolyte balance, and leading to dehydration. Without timely treatment, DKA may result in organ failure, brain swelling, impaired muscle function, or even death. Treatment involves immediate veterinary care, including fluid therapy to correct dehydration and electrolyte imbalances, insulin administration to stabilize blood sugar, and supportive therapies addressing underlying conditions. Close veterinary monitoring during recovery is necessary to ensure the pet stabilizes safely.
