Diabetes in dogs and cats can occur at any age. However, diabetic dogs are usually 4-14 years of age and most are diagnosed at roughly 7-10 years of age. Most diabetic cats are older than 6 years of age. Diabetes occurs in female dogs twice as often as male dogs. Certain breeds of dogs may be predisposed to diabetes.
Obesity is a significant risk factor for development of diabetes. As dogs and cats age, they may also develop other diseases that can result in diabetes or could significantly affect their response to treatment for diabetes, including overactivity of the adrenal gland in dogs (hyperadrenocorticsm) or overactivity of the thyroid gland in cats (hyperthyroidism), pancreatitis, heart disease, kidney disease, urinary tract infections and skin infections. The long-term use of medications containing corticosteroids is also a risk factor for diabetes.
