Understanding canine diabetes: A simple guide for pet parents

But here's the good news: Canine diabetes is manageable, and with the right information and a little dedication, your furry friend can continue to live a happy, full life. Our mission at My Diabetic Pet is to simplify this journey for you, just as we've learned to simplify it for Parker.

Here are the basics that we wished someone explained to us in plain language:

What exactly is canine diabetes?

Think of your dog's body like a finely tuned engine, and food as its fuel. When your dog eats, their body breaks down carbohydrates into glucose (a type of sugar), which is the primary fuel source for their cells.

To get this glucose from the bloodstream into the cells, the body needs a special "key" called insulin. Insulin is a hormone produced by the pancreas, a small but mighty organ located near the stomach.

In simple terms, canine diabetes occurs when:

1. The pancreas doesn't produce enough insulin (or any at all). This is the most common type in dogs, similar to Type 1 diabetes in humans. This is what happened with Parker. After a bout of pancreatitis, his pancreas just couldn't produce enough insulin anymore.
2. The body can't properly use the insulin it does produce. While less common in dogs, this is similar to Type 2 diabetes in humans.

Without enough working insulin, glucose can't get into the cells. Instead, it builds up in the bloodstream, leading to high blood sugar levels – and that's what we call diabetes.

Common signs your dog might have diabetes

Often, the first clues are changes you notice in your dog's daily habits. If you observe any of these, it's always best to talk to your veterinarian right away:

• Increased thirst (Polydipsia): Your dog seems to be drinking water constantly, emptying their bowl much faster than usual. This happened with Parker. He was drinking about a litre of water per day, which is a LOT for a 10 kg/23lb dog.
• Frequent urination (Polyuria): Because they're drinking more, they're also needing to pee more often, sometimes having accidents in the house.
• Increased qppetite (Polyphagia) with weight loss: This can be confusing! Your dog is constantly hungry because their cells aren't getting the glucose they need, so their body thinks it's starving. Yet, despite eating more, they might be losing weight because their body is breaking down fat and muscle for energy. Parker started to lose weight suddenly despite eating a proper diet and begging for treats and snacks.
• Lack of energy/lethargy: They might seem more tired, less playful, or generally "off."
• Sweet-smelling breath: This can be a sign of a more serious complication called diabetic ketoacidosis (DKA) and requires immediate veterinary attention.
• Cloudy eyes/cataracts: Diabetes can cause cataracts to develop very quickly. This was a significant issue for Parker; within weeks of his diagnosis, his eyes became cloudy, leading to cataract surgery.

What causes canine diabetes?

While the exact cause isn't always clear, several factors can contribute:

• Genetics: Some breeds are more predisposed (e.g., Golden Retrievers, German Shepherds, Poodles, Terriers like our Parker!).
• Pancreatitis: Inflammation of the pancreas can damage the insulin-producing cells, as it did in Parker's case.
• Obesity: Being overweight can make cells less responsive to insulin.
• Autoimmune Diseases: The body's immune system mistakenly attacks its own insulin-producing cells.
• Other Medical Conditions: Certain hormonal imbalances can play a role.
• Age: Diabetes is more common in middle-aged to older dogs. Parker was 11 1/2 when diagnosed.

How is canine diabetes treated?

The cornerstone of treating most diabetic dogs is insulin injections. Don't worry, it sounds scarier than it is! Your vet will teach you how to give these small, subcutaneous (under the skin) injections, typically twice a day, at home.

Beyond insulin, management also involves:

• Consistent Diet: A specific, consistent diet is crucial. Your vet will recommend the best type of food and a strict feeding schedule to help regulate blood sugar.
• Regular Exercise: Consistent, moderate exercise helps the body use glucose more efficiently. However, avoid intense, unpredictable bursts of activity that could drastically change blood sugar levels.
• Regular Monitoring: This includes blood glucose monitoring (at home or at the vet) and urine tests to track how well your dog's diabetes is being managed. This is where tools like our Free Blood Glucose Tracking Template can be incredibly helpful!

Can my dog live a normal life with diabetes?

Absolutely! With proper management, many diabetic dogs live long, happy, and fulfilling lives. It requires dedication, consistency, and a partnership with your veterinarian, but the effort is incredibly rewarding.

Parker, despite his diabetes, a torn CCL, and cataract surgery, still loves his walks, his squeaky toys, and snuggling with his humans. Managing his diabetes has become a part of our daily routine, not an overwhelming burden.
