Dogs are one of the most well-known domesticated species, with archaeological and historical records showing that they have lived in a mutually beneficial relationship with humans for thousands of years.
Male dogs are referred to as a dog, while a female is called a bitch. Offspring are called pups (or puppies) until around a year old. The collective noun for a group of offspring is litter.
Research has shown that it is probable that the first settlers respectively of the Americas and Australia brought dogs of some sort with them.
Scientific details
Dogs (scientific name Canis lupus familiaris) are a subspecies of wolves, divided into a multitude of different breeds all in principle capable of interbreeding (though in some cases, physical relations between representatives of two breeds are unlikely or problematic - Chihuahuas and Great Danes, for example).
Dogs are also viewed as being the single most genetically diverse species on Earth - largely thanks to human-imposed selective breeding, the vast array of dog breeds surpasses any other any other creature on the planet.
Bites
Despite being colloquially known as "man's best friend", every 40 seconds, someone in the United States seeks medical help for a dog bite, with approximately 800,000 such bites per year requiring medical attention.[1] Due to the high cost of dog bite liability claims, some insurance companies have blacklisted certain breeds and refuse to provide homeowner's insurance to those who own these dog breeds.

Uses
Dogs are used for many purposes:
- Guarding property and livestock.
- Herding sheep and cattle.
- Tracking by scent, carrying messages, and mountain rescue.
- Pursuing, flushing and retrieving game, and killing vermin.
- Providing assistance to blind and deaf people.
- Military and police duties including guarding, tracking and attacking. In World War II, the Soviet Union attempted to train dogs to place explosive charges under German tanks.
- To detect illegal drugs (German Shepherds are commonly trained to do so by police)
- As a beast of burden, or for drawing sledges and dogcarts.
- As a performing animal. Circus dogs have been trained to dance, ride bicycles and walk the tightrope.
- For fighting, now illegal in most places.
- As food. Dog is still considered a delicacy in China, Korea and parts of Africa today.
Today most dogs in western countries are kept for companionship only. Stray and feral dogs cause many problems, spreading diseases such as rabies, and attacking people and livestock.
