Domestication is a gradual process, so there is no precise moment in the history of a given species when it can be considered to have become fully domesticated. Zooarchaeology has identified three classes of animal domesticates: Pets (dogs, cats, ferrets, hamsters, etc.) Livestock (cattle, sheep, pigs, goats, etc.)
Domesticated worldwide Size: 120–180 cm (47–71 in) long, plus 7–15 cm (3–6 in) tail [204] Habitat: Savanna, grassland, desert, forest, and rocky areas [204] Diet: Grass, as well as a wide variety of vegetation [204] NE Unknown (about 1.2 billion used in farming) [205] Snow sheep.

Humans have introduced more different species to new environments than any single document can record. This list is generally for established species with truly wild populations— not kept domestically, that have been seen numerous times, and have breeding populations. While most introduced species can cause a negative impact to new ...
Because the evolution of domestic animals is ongoing, the process of domestication has a beginning but not an end. Various criteria have been established to provide a definition of domestic animals, but all decisions about exactly when an animal can be labelled "domesticated" in the zoological sense are arbitrary, although potentially useful.

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 ...
A feral animal is one that has escaped from a domestic or captive status and is living more or less as a wild animal, or one that is descended from such animals. [1] Other definitions [2] include animals that have changed from being domesticated to being wild, natural, or untamed.
Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million in total. Animals range in size from 8.5 millionths of a metre to 33.6 metres (110 ft) long and have complex interactions with each other and their environments, forming intricate food webs .
