Dog:The domestic dog ( Canis lupus familiaris or Canis familiaris). There are lots of races of dogs.For example:Shepherd dog,the bulldog and the Labrador. Dogs perform many roles for people, such as: hunting, herding, pulling loads, protection,assisting police and military, companionship and, more recently, aiding handicapped individuals. This impact on human society has given them the nickname "man's best friend" in the Western world. Extensive genetic studies undertaken during the 2010s indicate that dogs diverged from an extinct wolf-like canid in Eurasia 40,000 years ago.Sper că te-am ajutat!
