American Hairless Terrier: The American Hairless Terrier is a rare breed of dog that was derived as a variant of Rat Terrier.

Poochon: The Poochon (also known as Bichpoo, Bich-poo, Bichonpoo, Bichon-Poo, Bichoodle) is a crossbreed dog, the offspring of a Poodle and a Bichon Frise.  The Poochon became particularly popular through crossbreeding programs in Australia from the late 1990s.  Key to their development was the coordinated effort by Chevromist Kennels in Melbourne in bringing together various breeders aiming to develop the breed.  This breed of dog was developed to suit families wanting a small breed that was suitable for most people with allergies to dogs; the breeders were looking for a healthy, outgoing small dog with a non-shedding wool coat that would get along well with children They are very popular in Australia due to their exceptional temperaments, robustness and non-shed coats.  The Poochon typically has the shorter and more rounded muzzle of the Bichon Frise, and this can be seen from the time they are puppies.  Poochons have variable coat colours and markings.

Teddy Roosevelt Terrier: The Teddy Roosevelt Terrier is a small to medium-sized American hunting terrier.  Lower-set with shorter legs, more muscular, and heavier bone density than its cousin the American Rat Terrier.  There is much diversity in the history of the Teddy Roosevelt Terrier breed and it shares a common early history with the American Rat Terrier, Fox Paulistinha and Tenterfield Terrier.  It is said the Rat Terrier background stems from the terriers or other dogs that were brought over by early English and other working class immigrants.  Since the breed was a farm, hunting and utility dog there was little to no planned breeding other than breeding dogs with agreeable traits to each other in order to produce the desired work ethic in the dog.  It is assumed that the Feist (dog), Bull Terrier, Smooth Fox Terrier, Manchester Terrier, Whippet, Italian Greyhound, the now extinct English White Terrier, Turnspit dog and or Wry Legged Terrier all share in the Teddy Roosevelt Terrier's ancestry.  These early Ratting Terriers were then most likely bred to the Beagle or Beagle cross bred dogs (for increased scenting ability) and other dogs.  Maximizing the influences from these various breeds provides the modern Teddy Roosevelt Terrier with a keen sense of awareness and prey drive, an acute sense of smell and a very high intellect.  Although they tend to be aloof with strangers they are devoted companion dogs with a strong desire to please and be near their owners side at all times.

Yorkshire Terrier: The Yorkshire Terrier is a small dog breed of terrier type, developed during the 19th century in Yorkshire, England, to catch rats in clothing mills.

It is placed in the Toy Terrier section of the Terrier Group by the Fédération Cynologique Internationale and in the Toy Group or Companion Group by other kennel clubs, including the American Kennel Club.  A popular companion dog, the Yorkshire Terrier has also been part of the development of other breeds, such as the Australian Silky Terrier.  It has a grey, black, and tan coat, and the breed's nickname is "Yorkie".

Rare breed (dog): Rare breed (dog) is any breed of dog that is small in number and is used to refer to both old established breeds such as the Stabyhoun and Glen of Imaal Terrier or newer creations.  Since dogs have greater genetic variability than other domesticated animals the number of possible breeds is vast with new crosses constantly occurring, from these both selected and random crosses may come new breeds should offspring reliably breed true to type.  New breeds from the wild such as the Carolina Dog are quite rare compared to attempts at breed creation from man as found in the American Hairless Terrier which sought to exploit a mutation.
