Mortality and morbidity due to gastric dilatation-volvulus syndrome in pedigree dogs in the UK

J Small Anim Pract. 2010 Jul;51(7):376-81. doi: 10.1111/j.1748-5827.2010.00949.x.


Objectives: To estimate breed-specific risk of death due to, and prevalence of, gastric dilatation-volvulus (GDV) in UK pedigree dogs.

Methods: Data were available on the reported cause of and age at death and occurrence of and age at diagnosis of disease from the 2004 purebred dog health survey. A total of 15,881 dogs of 165 breeds had died in the previous 10 years; GDV was the cause of death in 65 breeds. There were 36,006 live dogs of 169 breeds of which 48 breeds had experienced > or =1 episodes of GDV. Prevalence ratios were used to estimate breed-specific GDV mortality and morbidity risks.

Results: Gastric dilatation-volvulus was the cause of death for 389 dogs, representing 2.5% (95% CI: 2.2-2.7) of all deaths reported and the median age at death was 7.92 years. There were 253 episodes in 238 live dogs. The median age at first diagnosis was five years. Breeds at greatest risk of GDV mortality were the bloodhound, Grand Bleu de Gascogne, German longhaired pointer and Neapolitan mastiff. Breeds at greatest risk of GDV morbidity were the Grand Bleu de Gascogne, bloodhound, otterhound, Irish setter and Weimaraner.

Clinical significance: These results suggest that 16 breeds, mainly large/giant, are at increased risk of morbidity/mortality due to GDV.
