The dog (Canis familiaris[4][5] or Canis lupus familiaris[5]) is a domesticated descendant of the wolf. Also called the domestic dog, it is derived from extinct Pleistocene wolves,[6][7] and the modern wolf is the dog's nearest living relative.[8] Dogs were the first species to be domesticated[9][8] by hunter-gatherers over 15,000 years ago[7] before the development of agriculture.[1] Due to their long association with humans, dogs have expanded to a large number of domestic individuals[10] and gained the ability to thrive on a starch-rich diet that would be inadequate for other canids.[11]
A typical pet lover is someone who loves animals in general. They have the tendency to be drawn to them by the mere fact that they are animals. Pet parents, on the other hand, have the same tendency but they also have an inherent bias that ties them to their own pets.
