Dog Definition

The dog is a mammal that has a very variable size, as there are small, medium and large breeds and each of them has been selected and domesticated by man for some purpose. Thus, there are presa dogs such as the American Stanford, the Brazilian fila or the bullmastiff. Some breeds have been trained as herding dogs (the Australian shepherd or the border colie).

Hunting is another function that dogs can perform (hounds, pointiers or beagles are especially gifted for this activity). The tasks that they can carry out are very diverse: as guide dogs for the blind, as police collaborators to detect drugs, to accompany people with physical limitations, to look for food, to help in rescue tasks, to detect cancer or as simple pets.

In any case, the dog is a very versatile animal and physiologically it has a very unique characteristic: very powerful olfactory receptors, to the point that its sense of smell is a million times superior to that of humans.
