American dog breeders Shelley Watts-Cross and David Turkheimer developed this large breed from American and European German Shepherd Dogs, Alaskan Malamutes, and Great Pyrenees. An official breed club was established in 1995.
The build of the King Shepherd is slightly long, robust and muscular; the structure is solid. The head is in good proportion to the body and moderately wide between the eyes. The forehead, seen from in front and in profile, is only slightly rounded, with or without a medial furrow, which is moderately well defined. The cheeks are not too full, are moderately curved and when viewed from the top should be much in the form of a "V", well filled in under the eyes. The thick firm ears are of medium size, moderately wide at the base, set on high and pointed; they are carried erect and slightly forward. (Puppies up to the age of 4-6 months, and sometimes older do not carry their ears completely erect). The eyes are medium size and almond-shaped set somewhat aslant and not protuberant, as nearly as possible matching the surrounding coat in shades of brown, and from very light to dark are acceptable. The chest is deep and broad. Thickly feathered, the tail reaches at least to the hocks. The tail is carried down and slightly curved; when excited or in movement, the dog raises the tail, which becomes more curved, without however going beyond the vertical. It must not, moreover, lie on or curl up on the back. Docked tails are inadmissible. The paws are round and short with a well closed, arched. The pads are very hard. The nails are short and strong, generally dark in color. Dewclaws are usually removed. The King Shepherd comes in a wide range of acceptable colors. These are as follows: Sable (a brownish tan with brown or black markings or a grayish silver with black markings); black saddle with tan, gold, cream, and tan or silver markings. Strong, rich colors and pigments are highly preferred. Small white spots on the chest are acceptable. Pale, washed-out colors are serious faults. The undercoat is invariably little colored, except in black dogs. White, blue, or liver colored dogs or a dog with a nose that is not black must be disqualified. Puppies change color from birth until they get their final coat. There are two coat varieties; coarse haired, which are straight and longhaired which are light and wavy.
