Dog

The dog (Canis familiaris when considered a distinct species or Canis lupus familiaris when considered a subspecies of the wolf)^[5] is a domesticatedcarnivore of the familyCanidae. It is part of the wolf-like canids,^[6] and is the most widely abundant terrestrial carnivore.^{[7][8][9][10][11]} The dog and the extantgray wolf are sister taxa as modern wolves are not closely related to the wolves that were first domesticated,^[12][13][14] which implies that the direct ancestor of the dog is extinct.^[15] The dog was the first species to be domesticated,^[14][16] and has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes.^[17]
