A dog is a domestic mammal of the family Canidae (Carnivora). It is a subspecies of the gray wolf and is related to foxes and jackals.
The dog is one of the two most ubiquitous and most popular domestic animals in the world while the Cat is the second.
For more than 12,000 years the dog has lived with humans as a hunting companion.
Dog Breeding
Human beings have played a major role in creating dogs that fulfill distinct societal needs. Through the most rudimentary form of genetic engineering, dogs were bred to accentuate instincts that were evident from their earliest encounters with humans. The first dogs were hunters with keen senses of sight and smell. Humans developed these instincts and created new breeds as need or desire arose.
Roles of Dogs in Human Society
Dogs have played an important role in the history of human civilization and were among the first domesticated animals.
They were important in hunter-gatherer societies as hunting allies and bodyguards against predators.
When livestock were domesticated about 7,000 to 9,000 years ago, dogs served as herders and guardians of sheep, goats, and cattle.
Dogs are mainly used for social purposes and companionship
Dogs are even used in therapy in nursing homes and hospitals to encourage patients toward recovery.
