Canidae is a family of mammals in the order Carnivora, which includes domestic dogs, wolves, coyotes, foxes, jackals, dingoes, and many other extant and extinct dog-like mammals. A member of this family is called a canid; all extant species are a part of a single subfamily, Caninae, and are called canines. They are found on all continents ...
Cerdocyonina is a natural lineage whose common ancestor was sister to the Eucyon–Canis–Lycaon lineage. It is represented in the fossil record by Cerdocyon 6–5 million years ago, and by Theriodictis and Chrysocyon 5–4 million years ago.
Canidae (/ ˈ k æ n ɪ d iː /; [3] from Latin, canis, "dog") is a biological family of dog-like carnivorans, colloquially referred to as dogs, and constitutes a clade. A member of this family is also called a canid (/ ˈ k eɪ n ɪ d /). [4] The family includes three subfamilies: the Caninae, and the extinct Borophaginae and Hesperocyoninae. [5]
Information about a species' reproductive biology may be critical to the success of a captive breeding program. [ 2 ] [ 3 ] [ 4 ] In some cases a captive breeding program can save a species from extinction , [ 5 ] but for success, breeders must consider many factors—including genetic, ecological, behavioral, and ethical issues.
A Czechoslovakian Wolfdog. The domestic dog (Canis familiaris) is a domesticated species of the gray wolf (Canis lupus), along with the dingo (Canis lupus dingo).Therefore, crosses between these species are biologically unremarkable and not a hybridization in the same sense as an interbreeding between different species of Canidae.
Horse breeders try to produce fast racehorses through breeding programs. Conservationists use breeding programs to try to help the recovery of endangered species by preserving the existing gene pool and preventing inbreeding .
An example of acceptable hog registration and identification standards by the Heritage Hog Breeders Club. See the American Border Collie Association's Registry on Merit Program. A near-comprehensive list of multi-breed registries operating in North America, flagging questionable registries, has been prepared by Canada's Guide To Dogs
A breeder is usually a purebred animal, bred with the intent of producing purebred, or even show-quality animals. However, in some cases, a breeding animal is crossbred with another breed or a mixed breed with the intent of combining aspects of two or more different breeds.
