  1. “the Bullmastiff is a crossbreed”
    This is wrong. The Bullmastiff is a *breed* that was created in the 1800s by crossing English Mastiffs (60%) and Bull Dogs (40%) to create a smaller, more aggressive Mastiff. It is a breed because it breeds true: breed two Bullmastiffs and all the puppies will be Bullmastiffs.

    Breed two crossbreeds such as the Labradoodle, and the mixed breeding will show in the variety of puppies: some pups will look like Labs, some will look like Poodles, some will look like Labradoodles, and some will look like “mutts.”
