Bullmastiff Large Dogs

Bullmastiff: The Bullmastiff stands about 25 to 27 inches tall and weighs between 110 and 130 lbs. This breed is confident and fearless, a natural guardian, but they are also calm and intelligent. Originally used to scare off poachers in 19th century England, the Bullmastiff breed now fills his time being an assistance animal, a police dog and a loyal family companion. (Photo credit: Reddogs/
