Briards are generally healthy.  The life expectancy for a Briard is 10-12 years.  Some lines are prone to eye disorders (PRA, cataracts, CSNB) and hip dysplasia.  Briards, like all breeds of dogs, are having occurrences of cancer, the most common of which in Briards is lymphoma, but also hermangiosarcoma, osteosarcoma, and mast cell tumors.  Briards, like other large-chested breeds, can experience bloat and stomach torsion.  The condition can come on very fast and, if left untreated, is fatal.
