Can someone explain what causes diabetes in dogs?

I've been reading up on diabetes in dogs and I'm still a bit confused about what actually causes it. From what I've gathered, it might have something to do with genetics and lifestyle factors. Can someone help me understand this better?

Diabetes in dogs, just like in humans, is a complex condition that can be influenced by both genetic and environmental factors. Some breeds are more prone to developing diabetes, such as Miniature Schnauzers, Pugs, and Bichons Frises. However, obesity is also a significant risk factor, as excess weight can lead to insulin resistance.

It's important to note that while genetics can play a role in the development of diabetes, it doesn't necessarily mean that a dog is guaranteed to develop the condition. A healthy lifestyle, including regular exercise and a balanced diet, can help reduce the risk of insulin resistance and promote overall health.

I think one common misconception is that diabetes is always preventable, but that's not entirely true. While a healthy lifestyle can certainly reduce the risk, some dogs may still develop diabetes due to genetic factors beyond our control. The good news is that with proper management and regular veterinary care, dogs with diabetes can still live long, happy lives.
