The Ambullneo Mastiff made its debut in the early 's in Southern California. This 57.5%, 42.5% Mastiff Bulldog breeding program and another decade passed before the F1 progeny was ready to be stored in the cryogenics bank. After testing for intelligence, hips, elbows and other physical abnormalities only the finest puppies and dogs were used. The breed is now in its 14th generation! A great dog for our times!
