Diabetes in American dogs is on the rise. Banfield Pet Hospital, a national veterinary hospital chain, has observed a 32 percent increase in canine diabetes cases since 2006 (cats had a 16 percent upsurge). Comparatively, incidences of the disease in humans have risen only 10 percent in the last four years.
Like humans, dogs can develop Type 1 or Type 2 diabetes. Unlike humans, however, Type 2 diabetes is relatively uncommon in dogs.
Type 1, which is caused by limited insulin production in the pancreas, has fewer preventable risk factors than Type 2. But reducing obesity in an overweight dog — a risk factor for both types of diabetes — may help lower his odds of developing this disease.
