The Bullmastiff can look intimidating, and for excellent reasons. They’re not afraid of anything and will get in the middle of danger to ensure that their family is safe. When they’re not guarding their home they’re pretty happy to be lapdogs, lounging on the couch with you while watching television. Because of this gentle side of their nature, they also make relatively good therapy dogs for those who need a little more help throughout their days. Unfortunately, the Bullmastiff is not a fan of other dogs and prefers to be the only dog in the home.
