A doghouse, known in British English as a kennel, is a small shed commonly built in the shape of a little house intended for a dog. It is a structure in which a dog is kept or can run into for shelter from the elements. It should not be too big or too small for the intended dog because of the potential for excessive heat loss or excessive constriction.
Archaeological evidence shows that dogs were quite prevalent in ancient Egypt, going back to 4500 BC or so, and were often held in high esteem as pets and hunting partners. Some dogs were even considered to be messengers of the gods. Egyptian nobility kept their hounds in mud-brick kennels, where the dogs were trained and cared for by professional dog trainers. These are some of the earliest known dog houses in the historical record.
Dogs were also an accepted part of ancient Chinese, Greek, and Roman societies and were often viewed as status symbols. Small dogs were popular as "companion dogs" spending much of their time living and sleeping under the same roof as their owner. The master's home was their home. Such was the life of the privileged pooch throughout the ages.
