THE
DEVELOPMENT
OF
THE VARIOUS BREEDS
To
understand the breeds, here is a very short history of the development of the different
types and uses of the dogs.
Through
the centuries, dogs have aided man in nearly all of his varied pursuits. Not
only has man’s best friend been the dog, but, generally speaking, the reverse
also holds true. As man spread out over the various regions of the earth, so did
his environments change and the sources of food supplies become more varied.
Adapting to both natural and man-made selection, dogs have evolved diversely,
learning to cope, with man’s changing needs and environments. The dog has a
large number of chromosomes for a mammal, which allows for an enormous possible
range of combinations of genetic material. Because of this the dog has the
ability to adapt rapidly to different climates throughout the world.
