The Anglo-Français de Petite Vénerie is a medium-sized breed of dog used in hunting as a scenthound, usually in packs.
 It is one of the Anglo-French hound breeds which were created by crossing French scenthounds with English (Anglo) foxhounds.
 The name "Petite Vénerie" does not mean that dogs of the breed are "petite" or small, but rather that it is used to hunt small game.
The Hawaiian Poi Dog (Hawaiian: "ʻīlio" or "ʻīlio mākuʻe" for brown individuals) is an extinct breed of pariah dog from Hawaiʻi which was used by Native Hawaiians as a spiritual protector of children and as a source of food.
The Marquesan Dog or Marquesas Islands Dog is an extinct breed of dog from the Marquesas Islands.
 Similar to other strains of Polynesian dogs, it was introduced to the Marquesas by the ancestors of the Polynesian people during their migrations.
 Serving as a tribal totems and religious symbols, they were sometimes consumed as meat although less frequently than in other parts of the Pacific because of their scarcity.
 These native dogs are thought to have become extinct before the arrival of Europeans, who did not record their presence on the islands.
 Petroglyphic representations of dogs and the archaeological remains of dog bones and burials are the only evidence that the breed ever existed.
 Modern dog population on the island are the descendants of foreign breeds later reintroduced in the 19th century as companions for European settlers.
The collie is a distinctive type of herding dog, including many related landraces and standardised breeds.
 The type originated in Scotland and Northern England.
 The collie is a medium-sized, fairly lightly built dog, with a pointed snout.
 Many types have a distinctive white pattern over the shoulders.
 Collies are very active and agile, and most types of collies have a very strong herding instinct.
 Collie breeds have spread through many parts of the world (especially Australia and North America) and have diversified into many varieties, sometimes with mixture from other dog types.
 Some collie breeds have remained as working dogs, used for herding cattle, sheep and other livestock, while others are kept as pets, show dogs or for dog sports, in which they display great agility, stamina and trainability.
 While the AKC has a breed they call "Collie", in fact collie dogs are a distinctive type of herding dog including many related landraces and formal breeds.
 There are usually major distinctions between show dogs and those bred for herding trials or dog sports.
 They typically display great agility, stamina and trainability and more importantly sagacity.

Anglo-Français and Français hounds are a general type of hunting dogs that include ancient French hounds and breeds created by mixing the French dogs with English (Anglo) Foxhounds.
 There are seven dog breeds that are described as Anglo-Français and Français hounds.
Paris' former Chemin de fer de Petite Ceinture ('small(er) belt railway'), also colloquially known as "La Petite Ceinture", was a circular railway built as a means to supply the city's fortification walls, and as a connection between Paris' railway termini.
 Built as two distinct 'Ceinture Syndicate' freight and 'Paris-Auteuil' passenger lines from 1851 that together formed an arc that surrounded the northern two thirds of Paris, it would become a fill circle of rail around the capital when its third Ceinture Rive Gauche section was built in 1867.
 Serving first as a freight-only line, then developing into a passenger service, the Chemin de fer de Ceinture became Paris' first metro-like urban transport.
 Much-frequented until its 1900 Universal Exposition peak, the Metro appearing that year would mark the onset of the Petite Ceinture line's decline.
The Tweed Water Spaniel, or Tweed Spaniel, is a breed of dog extinct since the 19th century.
 It is best known for being involved in the early development of the modern Curly Coated Retriever and Golden Retriever breeds of dogs.
 They were described as a generally brown athletic dogs from the area around Berwick-upon-Tweed near the River Tweed and close to the Scottish Borders.
 A type of water dog, the breed was not well known outside the local area.
 This breed may have been created by crossing local water dogs with imported St. John's water dog, another breed which is also now extinct.
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.
