Dogs have been domesticated by humans for over 5000 thousand years and throughout all of known history mankind has protected and nurtured this species. The bond between the two has been built over a long time and today they are the most common household pet. 

During humanities hunter- gatherer days, wolves developed a symbiotic relationship with the nomadic tribes order to survive. Humans got the benefit of a swift, agile, partner to help with hunting. Wolves gained a safe place to live and raise their pups, increasing the survival rate of their species. 

During the Medieval Age, European rulers often had permanent Hound Pens and a professional hound keeper who would take care of the ruler’s dogs. Kings and Lords spent large amounts of money on the upkeep of several hunting dogs to use on hunts and were even allowed near the high table, they became symbols of wealth and prestige. 

In the modern age, Dogs are no less resourceful to humanity. Police K9 units are used to sniff out drugs and track down criminals, the Army uses dogs to sniff out landmines which saves many lives. In domestic problems, service dogs are used to guide blind people, and are trained to help people who have panic attacks. 

In the normal household, they make great pets. Dogs can learn commands, follow the routines of their owners, and keep pests out of the house. Farm dogs, like the German Shepherd, are trained to heard sheep and chase away predators. 

Dogs have been a part of human evolution for 5 millennium and have earned in the nickname, Man’s Best Friend.
