A full black mask is also unacceptable. Some dark brindle coats may appear black unless examined in very bright light. A buckskin color pattern, where the base of the hair is fawn and the tips are black, may also appear solid black. A judge should not disqualify an American Bulldog for black color unless the dog has been examined in sunlight or other equally bright light.

Serious Fault: Less than 10% white markings.
Disqualifications: Solid black or blue with no white markings; tricolor (white with patches of black and tan); merle; full black mask.


With al the diversity of the breed standards breeders choose what fits the best for their own breeding program. When someone breeds full colored with 10% white marks dogs they are almost welcome with all registries, that is sadning and unacceptable.
The preserver of this wonderfull breed said this in an interview.

VAA: What do you think of an American Bulldog with less than 20% white?
JDJ: Well, it is very rare to get that much color and not typical for an American Bulldog. An American Bulldog is supposed to have a good deal of white. If you get a really good colored American Bulldog in every way, then you should breed it to a dog with less color. You can work it forward and backward; just like your size or just like you do your head, if your dogs get to small you breed to your bigger ones, if you get to much color breed them to white ones. But I’ve never seen that much color on a pure American Bulldog. If they have a lot of color they usually have mainly white on the head some white on the neck and chest, white on all four legs and belly and white on end of their tail. “

So people think twice before you buy an American Bulldog, do good research before you buy.
So called Special colors like blue, lilac, full colored black, black and tan or tri color are not American Bulldogs but crosses.
