Merle is a rare color for the American Bulldog, though it is not recognized as a standard color. Like any other merle-coated dog, a merle American Bulldog displays a mottled pattern with dark-colored patches throughout its body. The base color is often darker, with patches or spots of diluted colors like blue, bluish-gray, black, and brown.
A merle coat is typically associated with health risks, including vision and hearing problems. Still, with their rarity and attractive appearance, these puppies may cost on the higher side of the $1,200-$2,000 range for an average American Bulldog puppy.
