Which breed of dog is more diverse in terms of colors, the Stephens Cur  or the Chihuahua ?
Stephens Cur The Stephens Cur (a.k.a. Stephens' Stock Cur), is a scent hound that belongs to the Cur dog breed. They were originally bred by the Stephens family in southeastern Kentucky. The dogs known as "Little black dog" were bred by generations of that family for over a century. In 1970, they were recognized as separate and distinct breed of Cur. The dog is mostly black with white markings, but more than a third white is not permissible. It is good for hunting raccoon and squirrel, but can also be used to bay wild boar. They are registered with the United Kennel Club
Spaniel A spaniel is a type of gun dog. Spaniels were especially bred to flush game out of denser brush. By the late 17th century spaniels had been specialized into water and land breeds. The extinct English Water Spaniel was used to retrieve water fowl shot down with arrows. Land spaniels were setting spaniels—those that crept forward and pointed their game, allowing hunters to ensnare them with nets, and springing spaniels—those that sprang pheasants and partridges for hunting with falcons, and rabbits for hunting with greyhounds. During the 17th century, the role of the spaniel dramatically changed as Englishmen began hunting with flintlocks for wing shooting. Charles Goodall and Julia Gasow (1984) write that spaniels were "transformed from untrained, wild beaters, to smooth, polished gun dogs."
