Question: Which breed of dog is more diverse in terms of colors, the Stephens Cur  or the Chihuahua ? 
Context: The chizer is a mixed dog breed originating in the United States of America.  Chizers are a mix of the Chihuahua and the miniature schnauzer.  This breed is NOT recognized by the American Kennel Club.  The chizer has a combination of looks from both breeds of dogs, and can vary depending upon the breakdown of the breed.  General sizes of a chizer range between 6-14 inches in height and approximately 4-15-lbs in weight.  The chizer is a small breed dog, and works great in smaller areas, such as apartments, condos, and townhomes.  The chizer comes in a typical variety of colours, usually grey, black, brown or white.  This breed has a smooth, short haired coat that needs constant grooming, trimming around the eyes, ears and nose.  They are usually low to average shedding dogs, and typically most groomers leave their facial hair to mimic a schnauzer beard.  The ears of a chizer are medium in length and can stand erect when at attention, and their tail is usually docked.  The chizer can have either an apple shaped head, or round head, with either a long or short snout, giving it either the appearance of a Chihuahua or Miniature Schnauzer.  The body of the chizer is generally long and lean, with slender legs, and a square, robust back end.  This back end tends to make the dog sturdier, and gives them surprising jumping abilities to reach great heights. The Catahoula Cur is an American dog breed named after Catahoula Parish, Louisiana, United States.  Also known as the Catahoula Leopard Dog, it became the state dog of Louisiana in 1979.  The breed is sometimes referred to as the "Catahoula Hound" or "Catahoula Leopard Hound" because of its spots, although it is not a true hound but a cur.  It is also called the "Catahoula Hog Dog", reflecting its traditional use in hunting wild boar. Canine terminology in this article refers only to "dog terminology", specialized terms describing the characteristics of various external parts of the domestic dog, as well as terms for structure, movement, and temperament.  This terminology is not typically used for any of the wild species or subspecies of wild wolves, foxes, coyotes, dholes, jackals or the basal caninae.  Dog terminology is often specific to each breed or type of dog.  Breed standards use this terminology in the description of the ideal external appearance of each breed, although similar characteristics may be described with different terms in different breeds. The Chihuahua (Spanish: "chihuahueño" ) is the smallest breed of dog and is named after the state of Chihuahua in Mexico.  Chihuahuas come in a wide variety of colors, and two coat lengths. The term cur refers to the lowest class of nameless dog or Pariah Dog, generally a mixed-breed dog.  Originally the word "cur" referred to a certain English purpose-bred, short-tailed cattle driving dog known only from historical records, the cur dog, but in modern usage it applies to any mixed-breed. The Akita (秋田犬 , Akita-inu, Akita-ken ) is a large breed of dog originating from the mountainous northern regions of Japan.  There are two separate varieties of Akita: a "Japanese" strain, commonly called "Akita Ken" in Japan, "Akita Inu" ("inu" means "dog" in Japanese), or "Japanese Akita"; and an "American" strain, known as the "Akita" or "American Akita".  The Japanese strain called the Akita Inu comes in a narrow palette of colors, with all other colors considered atypical of the breed, while the American strain known simply as the Akita comes in all dog colors.  The Akita has a short double-coat similar to that of many other northern spitz breeds such as the Siberian Husky, but long-coated dogs can be found in many litters due to a recessive gene. A molera is a "hole" in a Chihuahua's head; it is the same as a fontanelle in human babies.  Historically, the Chihuahua as developed in Mexico and the United States has displayed a "hole in the head".  In times past, this has been accepted as a mark of purity for this dog breed, and it is still mentioned in most Chihuahua breed standards the world over.  The bones of the head in all foetuses are not firmly knitted together, but in most mammals, the different bones of the skull join with cartilaginous sutures as the animal matures.  The Chihuahuas' moleras vary in size and shape, occurring on the top of the head where the parietal and frontal bones come together. 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 The Treeing Cur is a breed of dog that originated in the mid-west and was first recognized by United Kennel Club on November 1, 1998, due to the efforts of Alex and Ray Kovac.  "Most Cur breeders were not well off and so they required a dog that could serve multiple purposes: hunter, guardian, and stock dog.  The result was the Treeing Cur, "which is the most varied in size and colors of the Cur breeds", according to United Kennel Club.They are primarily used to tree squirrels, raccoons, opossums, wild boars, bears, mountain lions and bobcats as well as to hunt big game. The Mountain Cur is a type of working dog that is bred specifically for treeing and trailing small game, like squirrel and raccoons.  They are also used for hunting and baying big game like bear and wild boar as well as being an all-purpose farm dog.  Curs are a member of the Hound group, and the Mountain Cur is one of several varieties of cur.  It can also be used as a water dog.  Mainly bred in Ohio, Kentucky, Virginia, and Tennessee, it has been registered with the United Kennel Club since 1998.  The Mountain Cur Breeder's Association was formed in 1957.
