Why Poodles have curly hair

Poodles have curly hair, because they bred them with two other dogs that would make them have curly hair, so that they could be used as water dogs. There are two different reasons why having curly hair would help them to be a water dog. One, when they come out of the water their hair would dry quickly. Two, when it's cold in the water there skin stays warm and dry, because the water runs through their "fro".
