Anywhere between 1 in 100 to 1 in 500 dogs develops diabetes,1 and those numbers are expected to increase. While any dog can develop diabetes, it frequently affects middle-aged to older dogs, especially unspayed female dogs.
The primary cause of canine diabetes is largely unknown, but experts suggest that genetics may play a role.
If you feel your dog is at risk for developing diabetes, consider having your pet tested during a regular veterinary examination at least once a year.
