When we met our neighbors first bullmastiff, he told me they were known for actually bulldozing into a intruder and knocking them down. And then holding them at bay by standing or laying on them! I know the one they have now can hold me down! LOL he said they're not overly aggressive, but their size and demeanor is a good deterrence.From what I've seen these intimidating looking dogs rely on appearance and size for warding off attacks.



I've only seem them about 70-80 lbs. For whatever reason they are almost popular around here.
