American Bulldog Breed Description - Cross #1

The American Bulldog is a stocky, well-built, strong-looking dog, with a large head and a muscular build. The shoulders and chest tend to be the most muscular parts of the American Bulldog. Its coat is short and generally smooth, requiring little maintenance except a bath every few weeks. The breed is a light to moderate shedder. Colors, while historically predominantly white with patches of red, black, or brindle, have grown in recent years to include many color patterns including black, red, brown, fawn, and all shades of brindle. The color conformation is quite varied. Black pigmentation on the nose and eye rims is traditionally preferred, with only some pink allowed. Eye color is usually brown, but heterochromia also occurs. American Bulldogs are known to drool more than other breeds of dog. The Bully type is generally a larger, heavier dog with a shorter muzzle, but the muzzle should never be so short that it causes difficulty with breathing. Standard types are generally more athletic with longer muzzles and a more square head. Many modern American Bulldogs are a combination of the two types, usually termed "hybrid." In general, American Bulldogs weigh between 27 and 54 kg (60 to 120 lb) and are 52 to 70 cm (20 to 28 in) at the withers, but have been known to greatly exceed these dimensions, especially in the "out of standard," nonworking stock.

Mastiff Breed Description - Cross #2

The English Mastiff, or simply the Mastiff, is a British dog breed of very large size. Likely descended from the ancient Alaunt and Pugnaces Britanniae, with a significant input from the Alpine Mastiff in the 19th century. Distinguished by its enormous size, massive head, short coat in a limited range of colors, and always displaying a black mask, the Mastiff is noted for its gentle and loving nature. The lineage of modern dogs can be traced back to the early 19th century, but the modern type was stabilized in the 1880s and refined since. Following a period of sharp decline, the Mastiff has increased its worldwide popularity. Throughout its history the Mastiff has contributed to the development of a number of dog breeds, some generally known as mastiff-type dogs or, confusingly, just as "mastiffs".

It is the largest living canine, outweighing the wolf by up to 50 kg (110 lbs) on average.

With a massive body, broad skull and head of generally square appearance, it is the largest dog breed in terms of mass. It is on average slightly heavier than the Saint Bernard, although there is a considerable mass overlap between these two breeds. Though the Irish Wolfhound and Great Dane can be more than six inches taller, they are not nearly as robust.

The body is large with great depth and breadth, especially between the forelegs, which causes these to be set wide apart. The length of the body taken from the point of the shoulder to the point of the buttock is greater than the height at the withers. The AKC standard height (per their website) for this breed is 30 inches (76 cm) at the shoulder for males and 27.5 inches (70 cm) (minimum) at the shoulder for females. A typical male can weigh 150–250 pounds (68–113 kg), a typical female can weigh 120–200 pounds (54–91 kg), with very large individuals reaching 300 pounds (140 kg) or more.
