Dogs have been domesticated by Man for thousands of years. There are hundreds of breeds of dogs.
Some dog breeds are small like Boxers and Terriers.nbsp; Other breeds of dogs are large, such as Saint Bernards
and German Shepards. Dogs of this size can weigh a hundred pounds or more. Besides just being pets, many
dogs earn their living doing tasks such as pulling sleds, sheparding sheep, and retrieving game fowl on hunts.
