Belgian Shepherd Dog

Mortality
Median longevity of Belgian Shepherds (all varieties combined) in the 2004 UK survey, was 12.5 years, which is on the high side, both for purebred dogs in general and for breeds similar in size. The longest-lived of 113 deceased Belgians in the UK survey was 18.2 years. Leading causes of death were cancer (23%), cerebral vascular, i.e., stroke (13%), and old age (13%).

Average longevity of Belgian Tervurens in the 2003 American Belgian Tervuren Club survey was lower, at 10.6 years, than in the UK survey. The difference in surveys does not necessarily mean Belgian Tervurens live shorter lives than other varieties of Belgian Shepherds. Breed longevities in USA/Canada surveys are usually shorter than those in UK surveys. Leading causes of death in the 2003 American Belgian Tervuren Club survey were cancer (35%), old age (23%), and organ failure (heart, kidney, liver) (13%).

Morbidity
Belgian Shepherds are afflicted with the most common dog health issues (reproductive, musculoskeletal, and dermatological) at rates similar to breeds in general. They differ most notably from other breeds in the high incidence of seizures and/or epilepsy. In the UK survey of Belgian Shepherds and both the 1998 and 2003 ABTC survey of Belgian Tervurens, about 9% of dogs had seizures or epilepsy.

Other studies have reported rates of epilepsy in Belgian Tervurens as high as 17%, or about one in six dogs. For comparison, the incidence of epilepsy/seizures in the general dog population is estimated at between 0.5% and 5.7%.
