The settlers crossbreed their dogs with well-adapted swamp hunting wolf dogs owned by Native Americans in an effort to develop a better working dog. Catahoulas come in many different colors including blue merle, red merle, brindle, and solid colors. Often, solid coat Catahoulas have small splashes of other colors such as white on their face, legs or chest. Though most dogs have webbing between the toes, Catahoulas' feet have more prominent webbing which extends almost to the ends of the toes. This foot gives the Catahoula the ability to work marshy areas and gives them great swimming ability.
