Dobes are the only breed of dog created solely for the purpose of guarding people from other bad people.
People have no idea the sheer variety of relatively exotic mastiff/ Molosser-type dogs here, now.
Of all crazy things, one day in Tractor Supply, I met a couple with two Boerboels.
Happily, they were responsible owners and the dogs were friendly and well behaved.
A Boerboel would simply swallow the average pit.
My wife and I breed beagles. My wife and daughter breed Dobermans. They show both at AKC confirmation shows like you see on TV.
I remember the first time I saw a Neapolitan Mastiff. It was 165 pounds. Its head was about 1 1/2 feet long. However, it was a big gentle slobber dog. Too much drool for me. He showed it at Westminster that year. It is one of the only Neapolitan Mastiffs on the show circuit. It made other mastiffs and working dogs varieties look small.
