Merle is a unique coloration of the American bulldog, not recognized as its standard color though. Like any other merle breed, merle-colored American bulldogs would have a mottled or patched appearance throughout their body. They would have a black or brown coat at the base with patches of diluted colors like blue, bluish-gray, or red. They aren’t too easy to get and even cost a lot, as high $2000.
Blue Merle
For blue merle American bulldogs, their coat is partially black, teamed with a bluish-gray coloration, creating a mottled pattern.
