Can a dog get diabetes?

If you’ve ever caught yourself worrying about your pup’s sudden thirst or weight loss, you might have wondered about their health—including whether dogs can develop diabetes. The short answer is yes, just like humans, dogs can get diabetes, and it’s more common than many new owners realize.

Diabetes in dogs happens when their bodies can’t regulate blood sugar properly, usually because their pancreas doesn’t make enough insulin or their cells don’t respond to it. This often ties to lifestyle factors: dogs that get little exercise, eat high-carb diets, or are overweight are at higher risk. For example, a Lab that spends most days napping on the couch and gets table scraps regularly is more likely to face this issue than an active terrier that sticks to a balanced dog food.

As a new owner, there are simple steps to lower your dog’s risk. First, stick to portion-controlled, vet-recommended dog food—avoid sharing too many human snacks, especially sugary ones like cookies. Second, aim for daily activity: even 20-minute walks twice a day or a game of fetch in the park helps keep their weight in check and their metabolism healthy. Regular vet checkups are also key; vets can spot early signs like increased urination or fatigue before the condition worsens.

It’s also important to follow local rules that tie into your dog’s health. In most U.S. cities, for example, you’re required to keep your dog on a leash in public areas—this isn’t just about safety, but also ensures they get consistent exercise instead of wandering aimlessly. You’ll also need to clean up after your dog during walks, which keeps public spaces clean and prevents the spread of germs that could affect their health. And remember: positive training (using treats and praise instead of punishment) reduces stress, which is good for their overall well-being, including their metabolic health.

If your dog does get diagnosed with diabetes, don’t panic. With vet care—like insulin shots, a tailored diet, and regular blood sugar checks—many dogs live happy, active lives. The key is catching signs early and staying consistent with their care routine. For example, a friend’s Cocker Spaniel was diagnosed two years ago; with daily insulin and a low-carb diet, he still loves his morning walks and playing with his favorite toy.

Taking care of a dog means staying attuned to their health needs, from daily walks to watching for unusual behaviors. By staying proactive and following both vet advice and local rules, you’ll help keep your pup healthy and by your side for years to come.
