Lifespan
The median longevity of Belgian Shepherds in a recent study was 12.5 years. This is above average, both for purebred dogs in general, and for breeds similar in size. The longest-lived of 113 dogs in the survey was 18.2 years.
Common Disorders
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 a UK survey of Belgian Shepherds, 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%.
Potential Hereditary Defects and Disorders
- Epilepsy: Seizures; convulsions
- Lymphedema: Swelling and pitting of the legs, usually hind legs, caused by abnormally developed lymph vessels.
- X-linked Muscular Dystrophy: Causes a stiff gait ("bunny hop"). Appears at 6-9 weeks of age.
