Vet Bob O’Brien on Preventing Diabetes in Dogs, Cats & Rabbits

November 17, 2025

Nobody wants to think about their beloved pet developing diabetes, but the reality is that our four-legged (and occasionally long-eared) companions are facing some of the same health challenges as their humans. The good news? The risk of pet diabetes can often be significantly reduced with some thoughtful lifestyle choices.

In this article, our Vet Bob O’Brien explains what’s behind the onset of diabetes and how you can plan ahead to prevent it. Want to get your pet into a healthy routine to keep future issues at bay? Book a health check-up and let our vets in Wincanton help you plan for a long life together.

Understand pet diabetes and risk reduction measures

Understanding the real culprits

Diabetes isn’t caused by too many biscuits, though your dog’s dramatic begging might suggest otherwise. Bob explains that the condition occurs when the body can’t properly regulate blood sugar levels, but the underlying causes are more complex than sweet treats.

Dogs typically develop Type 1 diabetes (their pancreas stops producing insulin), whilst cats usually face Type 2 diabetes (their bodies become resistant to insulin). Rabbits can develop either type, though it’s relatively uncommon in our hoppy friends.

Factors that can increase the risk of pet diabetes:

  • Genetics plays a starring role, with breeds like Golden Retrievers, Samoyeds and Burmese cats facing higher risks.
  • Age is another significant factor with middle-aged to senior pets being more vulnerable.
  • Female dogs, particularly unspayed ones, also face increased risk due to hormonal fluctuations.

The weight of the matter

Here’s where prevention gets serious: obesity is the biggest controllable risk factor. Those extra pounds aren’t just affecting your pet’s ability to chase balls around Wincanton or fit through the cat flap – they’re actively working against their metabolism.

Fat tissue produces hormones that interfere with insulin function, creating a perfect setting for diabetes development. The solution sounds simple but requires dedication: maintaining an ideal body weight through portion control and regular exercise. Yes, even if your cat perfects their ‘starving’ expression when you measure their food.

Movement matters more than you’d think

Regular exercise isn’t just about burning calories – it actually improves insulin sensitivity, helping the body use glucose more effectively.

  • Dogs need daily walks around Wincanton that go beyond garden inspection duties.
  • Cats benefit from interactive play sessions that tap into their hunting instincts.
  • Rabbits require space for hopping, jumping and performing their delightfully ridiculous binkies.

Our Vet Bob shares how even modest increases in activity can make significant differences to long-term health outcomes.

Quality nutrition without the drama

Focus on species-appropriate, high-quality diets rather than obsessing over individual ingredients. Consistent meal timing helps regulate natural blood sugar patterns, whilst avoiding dramatic weight fluctuations keeps metabolism steady.

  • For dogs, stick to measured portions of quality commercial food. 
  • Cats need protein-rich diets that mirror their carnivorous nature.
  • Rabbits thrive on unlimited timothy hay, controlled pellet portions, and appropriate fresh vegetables.

The monitoring advantage

Regular veterinary check-ups at Southill Vets become your secret weapon in diabetes prevention. Annual blood tests can detect early metabolic changes, giving you time to implement protective measures before problems develop. Bob suggests watching for subtle changes in behaviour – increased drinking, frequent urination, unexplained weight loss despite a good appetite or unusual lethargy often signal trouble long before obvious symptoms appear.

Prevention pays dividends

Small, consistent efforts compound over time. Measure portions, increase activity gradually, and resist those expert-level pleading techniques your pets have perfected. A healthy diet and weight management today can support your pet’s wellbeing for years to come. While some pets with diabetes will still require insulin, maintaining a healthy lifestyle helps optimize their overall health.
