Breed Specific Dog Diseases: Smaller Breeds Have Higher Rates of Diabetes And Cushing's Syndrome

University of Georgia researchers, studying more than 75,000 dogs from 82 breeds, have found that the causes of canine deaths vary by breed as well as age (1). The study revealed that congenital diseases, trauma and infection are the most frequent causes of deaths in dogs under 2 years old and that cancer risk peaks at about age 10.

The researchers also determined that bigger dog breeds are more vulnerable to musculoskeletal disease, gastrointestinal disease, and cancer. Smaller breed dogs, on the other hand, are more at risk for endocrine and metabolic diseases such as diabetes mellitus and Cushing's disease (1).

It has long been recognized that there are patterns in the causes of death for our dogs. This study helps owners know what sort of problems to watch out for in their pets. It helps veterinarians focus on the most likely cause of a particular dog’s illness. And most importantly it guides us in identifying specific risks for individual patients and taking action to minimize these and prevent or delay illness and death.
