Dogs provide companionship, therapy to depression, and safety to danger- providing both physical and psychological support and supplement to humans. The history of such friendly canines and the originality, evolution and domestication of it is an interesting topic to investigate upon. First of all, the diverse range of dogs comes from one common ancestor of gray wolves. By comparing the DNA of domesticated dogs and gray wolves, scientists have safely traced the origin of dogs as middle-eastern wolves. At least 15,000-16,000 years ago, one pack or several packs of wolves which were especially curious and attracted to human camps found food in the human dumps. They were given the

The physical appearance that the humans wanted of the bulldogs resulted in cardiac and respiratory disease, because it is not easy for a bulldog to breathe easily through their short and squished noses. Their shorter legs also create health problems, giving rise to the question whether we have overbred dogs.
