Please do not let this thread about my new pup get to dramatic (you know who you are reading this), but the American Mastiff is a relatively new breed (about 25yrs running). Not AKC recognized, but started as a cross between OEM and Anatolian. Pretty much looks just like OEM, but for the most part has tighter bottom lip eliminating SOME of the excess drool. Again, I don't want my happy announcement thread to get dramatic. I know a lot of people have VERY intense convictions about this breed. Most important to me, he is a loving sweet happy pup!
