The Poodle's history is shrouded in antiquity and hypothesis. By the 15th

writings and in art work It is believed by some that the poodle is the original
water spaniel. It is known that the Poodle was, and even today, is used as a
working hunter and duck retriever. The very stylish hair trim that is
distinctive with the Poodle, and seen in conformation, actually has a real
function and purpose. The Poodle's coat protects the dog from water and debris
in the water, it buoys the dog, and adds insulation to keep the joints, and the
rest of the dog, warm while working.

explains why most show and circus dogs belong to this breed because their
learning is very quick and consistent
