Breed Standards for the Ambullneo Mastiff

General Appearance:

The Ambullneo Mastiff is a highly intelligent, unstoppable guardian. This 90’s version of the Bullmastiff comes from a breeding program started in the early 80’s comprised of breeding an English Mastiff male to a Neapolitan female where two pups from this litter were then bred to a Game Bred Pitbull. These 50/50 crosses were bred to a Bullmastiff. The result was a 45% Bulldog, 55% Mastiff cross. An American Bulldog/Pitbull was bred to a Bullmastiff producing a 70% Bulldog, 30% Mastiff cross. This was bred to the 45% Bulldog, 55% Mastiff cross to produce a 57.5% Bulldog, 42.5% Mastiff.
