Care Tips

Mastiffs are gentle giants that need moderate daily exercise but should not be over-exercised as puppies to protect their developing joints. Their heavy jowls produce significant drool and require regular wiping. Due to their giant size, they are prone to joint disease and bloat, and their lifespan is unfortunately short.
