Siberian huskies have an average lifespan of between 12 and 15 years. They are generally considered a healthy breed and are not especially prone to any life-threatening hereditary illnesses.
Huskies that are used in the racing industry, however, can develop illnesses from the exertion, including gastric and respiratory diseases that lower their quality of life. Huskies are also notorious escape artists, and running away from home puts them at risk for an early death through accident or contracting a communicable disease from contact with other animals.
Purebred huskies are screened by Orthopedic Foundation for Animals for a canine version of von Willebrand Disease, a genetic illness that hinders blood clotting; however, this genetic disease is rare within the breed. A healthy, well-cared-for husky that does not escape from its home can expect to live out its natural lifespan.
