What two dogs make a bull- mastiff?

Answer 1

The Bullmastiff breed, is a combination of the Mastiff and the Bulldog. This breed was in created in England around 1850 and it's the only guard dog created there. The Alpine Mastiff was an extinct breed originating in Switzerland but the Saint Bernard was also known as the Alpine Mastiff. America has it's matiff called The American Bandogge Mastiff which looks like a mastiff mixed with pitbull and even share the blue color of the pitbulls. The Argentian dogo is also called the Argentian mastiff.

This is to show that the mastiff breed was paramount for developing the kinds of mastiff breed around the world.

Answer 2

Nobody knows. Not only is the American bulldog's history not well documented, but there are alsodifferent"types" of American bulldog which look very distinctly different, suggesting that more then just 2 breeds where tossed together to make them. Like many dogs bred to work on farms, especially in early America, chances are the dogs whereoriginallya mix of anything and everything and keeping only the dogs that did the job. In the Amer. bullies case that job was to find stray animals or wild boars, catch them and keep them alive till the farmer or hunter came along.

Due to their bully like features, especially ones of the Johnson variety, it can almost be safely assumed that they descended from the Old English Bulldog, and many speculate that they are also part mastiff. The old southern and standard type more then likely also haveLabradorin their lineage. Of course, once again, since theyweren'treally documented and when using dogs to work was still a huge deal, nobody really cared about keeping dogs as purebreds, they only cared if the dog did it's job, so mixing dogs was very common. So while Old English Bulldog, Mastiff and Labrador are good guesses and theories, they are just theories.
