Research shows that domestication occurred about 27,000–40,000 years ago. Until then, no other animal lived with or interacted closely with humans. It all began when wolves started appearing near human dwellings in search of leftover food. In return, they would help humans hunt. Over the next thousands of years, the wolf gradually evolved into the modern dog as we know it today.

Seventy percent of people include their dog’s name on their holiday cards.

They may not look like us, but our dogs are more similar to us than we like to admit. They are social beings, see us as family members, crave attention, and experience many of the same emotions we do — just to name a few. These qualities explain why the two species form such an intense and inseparable bond.

One of the reasons dogs make such amazing pets is that they are highly skilled at reading human emotions. They combine their senses of sight and hearing to interpret what their owners are going through. According to the AKC, these wonderful dogs can recognize six different emotions: anger, sadness, surprise, fear, happiness, and disgust.
