Bullmastiff breed information
A confident combination of the Bulldog and the Mastiff, the Bullmastiff is a powerful dog with a big head and pointed, floppy ears. Originally bred as guard dogs in England, adult Bullmastiffs weigh between 100 to 130 pounds—so it’s easy to see why they can be intimidating. Experienced trainers are recommended for these puppies to make sure understanding of basic commands and socialization skills are in place before the Bullmastiff becomes too big to handle! Loving and quite docile despite their size, these dogs can make sweet family guardians.
