Brief info: The Old English Mastiff is a massive dog. The Mastiff has a large, heavy square head with a well marked stop between the eyes.
The muzzle should be half the length of the skull. The medium-sized brown to dark hazel eyes are set wide apart with a black mask around them. The nose is dark in color.
The small ears are V-shaped and in proportion with the skull and are dark in color. The teeth should meet in a scissors bite but a slightly undershot bite is also acceptable in the show ring providing the teeth do not show when the mouth is closed. The tail is high-set with a wide base, tapering to a point reaching the hocks. Coat colors include golden fawn, light fawn, apricot, silver, tiger or brindle.
