The relationship between humans and dogs can be traced back to at least
15,000 years ago, to the Bonn-Oberkassel dog, who was found buried
alongside two humans.
For centuries, dogs have been considered man's best friend. This is most
evident in western countries, such as the United States, where over 48% of
households have a pet dog.
Studies have demonstrated that both dogs and humans release oxytocin while
spending time together. This release of oxytocin is correlated with the
formation of a strong social bond. Canines are capable of discriminating
between positive and negative human facial expressions and will react
accordingly.
Dogs appear in religions all over the world, particularly in Mesoamerican
folklore and myth, signifying the deep reverence humans all over the world
and throughout history have for them.
