1,914 dogs of the following breeds were included in this study: Akita, Bloodhound, Collie, Great Dane, Irish Setter, Irish Wolfhound, Newfoundland, Rottweiler, Saint Bernard, Standard Poodle, and Weimaraner which was performed as a prospective cohort study.
Owners of dogs that did not have a history of GDV were recruited at dog shows, and the dog`s length and height and depth and width of the thorax and abdomen were measured.
Information concerning the dogs` medical history, genetic background, personality, and diet was obtained from owners, and owners were contacted by mail and telephone at approximately 1-year intervals to determine whether dogs had developed GDV or died.
Incidence of GDV based on the number of dog-years at risk was calculated for each breed, and breed-related risk factors were identified.
RESULTS AND CLINICAL RELEVANCE: Incidence of GDV for the 7 large (23 to 45 kg [50 to 99 lb]) and 4 giant (> 45 kg [> 99 lb]) breeds was 23 and 26 cases/1,000 dog-years at risk, respectively.
Of the 105 dogs that developed GDV, 30 (28.6%) died. Incidence of GDV increased with increasing age.
Cumulative incidence of GDV was 5.7% for all breeds.
The only breed-specific characteristic significantly associated with a decreased incidence of GDV was an owner-perceived personality trait of happiness.
