Dogs come not only in different breeds (there are hundreds if not
thousands of breeds of dog), but different types as well. And no, not
"big and little" or "short hair or long haired", although those
occasionally play a part in how the animal will be classified. The type
of dog is determined on what the dog will be used for. The two main
types of dog are working dogs and non-working dogs, but these are split
into several categories, each with their own subcategories.
