Human–canine bond
Human–canine bonding is the relationship between dogs and humans. This relationship 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.The human–canine relationship is not necessarily always a positive one; dogs can be viewed in an extremely negative light depending on the region. On average, females tend to have more positive attitudes toward dogs as opposed to males, and studies have demonstrated that both dogs and humans release oxytocin while spending time together.
