Any one out there own an ENGLISH mastiff?

erm...the first thing you should learn is that the "english" mastiff IS the mastiff. "english" is a descriptive word for that particular breed, but the breed is actually the Mastiff. Anyone who sells them using the "English" moniker is a BYBer. If the breeder is so wonderful, they should be able to answer all your questions and tell you about the parent's OFA certifications, champion titles, and what health guarantee they are giving you. a href="http://www.akc.org/breeds/mastiff/" rel="nofollow"http://www.akc.org/breeds/mastiff//a
