Do Rottweilers come in any other colours than black with tan, rust or mahogany markings?
Generally speaking, no, Rottweilers do not come in any other colour. If you see or hear of a purebred Rottweiler that is a different colour then, again, a recessive gene has surfaced and it is considered unacceptable. As recently as 1901, Rottweilers were accepted in other colours though “black with russet or yellowish markings” was still preferred. As breed standards were developed, the now familiar black with rust or mahogany markings was established as the desired colour. Only an unscrupulous breeder would breed dogs, or continue to breed dogs that produced anything other then the desired black and tan, rust or mahogany markings. As mentioned in #13, any dog that deviates from this standard should be spayed or neutered.
