Their long relationship with humans has led dogs to be distinctively attuned to real human behavior and they are able to prosper on the starch-rich diet that would be inadequate for other canid types. Dogs vary widely in shape, size and colours. Dogs perform many roles for people, such as hunting, herding, pulling loads, protection, assisting police and military, companionship and, recently, aiding handicapped individuals. This influence on human world has given them the sobriquet "man's best friend".
The word "domestic dog" is generally used for both domesticated and feral kinds. The English expression dog comes from Middle English dogge, from Old English docga, a "powerful dog breed". The word may are based on Proto-Germanic *dukk?n, represented in Old English finger-docce ("finger-muscle"). The word also shows the familiar petname diminutive -ga also seen in frogga "frog", picga "pig", stagga "stag", wicga "beetle, worm", amongst others. The term dog may finally derive from the earliest layer of Proto-Indo-European vocabulary.In 14th-century Britain, hound (from Old English: hund) was the overall word for all home canines, and dog referred to a subtype of hound, a blended group including the mastiff. It is believed this "dog" type was so common, it eventually became the prototype of the category "hound". From the 16th hundred years, dog had end up being the general term, and hound experienced begun to refer and then types used for hunting.[ The word "hound" is ultimately derived from the Proto-Indo-European term *kwon-, "dog". This semantic move may be compared to in German, where the matching words Dogge and Hund retained their original meanings.A male canine is known as your dog, while a lady is called a bitch. The father of any litter is called the sire, and the mother is named the dam. (Middle English bicche, from Old British bicce, ultimately from Old Norse bikkja) The process of beginning is whelping, from the Old English word hwelp; the modern English word "whelp" can be an alternate term for puppy. A litter refers to the multiple offspring at one birth which are called young puppies or pups from the French poup?e, "doll", which has generally replaced the elderly term "whelp".The dog is grouped as Canis lupus familiaris under the Biological Types Concept and Canis familiaris under the Evolutionary Species Concept.In 1758, the taxonomist Linnaeus shared in Systema Naturae a categorization of kinds including the Canis species. Canis is a Latin term meaning dog, and the list included the dog-like carnivores: the home dog, wolves, jackals and foxes. The dog was classified as Canis familiaris, this means "Dog-family" or the family dog. On the next page the wolf was recorded by him as Canis lupus, this means "Dog-wolf". In 1978, an assessment aimed at minimizing the number of recognized Canis varieties suggested that "Canis dingo is now generally seen as a distinctive feral home dog. Canis familiaris can be used for domestic canines, although taxonomically it should oftimes be synonymous with Canis lupus." In 1982, the first edition of Mammal Species of the planet listed Canis familiaris under Canis lupus with the comment: "Probably ancestor of and conspecific with the domestic dog, familiaris. Canis familiaris has site goal over Canis lupus, but both were shared all together in Linnaeus (1758), and Canis lupus has been universally used for this species", which averted classifying the wolf as the family dog. The dog is currently listed among the countless other Latin-named subspecies of Canis lupus as Canis lupus familiaris.In 2003, the ICZN ruled in its Thoughts and opinions 2027 that if wild animals and their domesticated derivatives are regarded as one species, then your scientific name of this species is the medical name of the untamed pet. In 2005, the 3rd release of Mammal Varieties of the globe upheld View 2027 with the name Lupus and the take note: "Includes the local dog as a subspecies, with the dingo different - artificial variations created by domestication and selective breeding" provisionally. However, Canis familiaris may also be used due to an ongoing nomenclature debate because wild and domestic animals are separately recognizable entities and that the ICZN allowed users an option concerning which name they could use, and lots of internationally recognized researchers would prefer to use Canis familiaris.
