Eye color is usually brown, but heterochromia also occurs, although this is also considered a cosmetic fault. 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.' The color conformation is quite varied, but solid black or any degree of merle is considered a cosmetic fault, and a blue color is a disqualification by the National Kennel Club Breed Standard.
