Approximately one in 500 dogs develops diabetes and that number is on the rise. While any dog can develop diabetes, it frequently affects middle-aged to older dogs, especially unspayed females.

The primary cause of canine diabetes is largely unknown, but experts suggest that genetics may play a role. Overweight dogs also are at risk for developing diabetes. If you feel your dog is at risk for developing diabetes, consider having your pet tested once a year during a regular veterinary examination.
