She thinks she is a WATER dog like a Chessie or Nova Scotia Duck Tolling Retriever. Tell her she's a poodle with beautiful bouncy curly hair. Poodles don't do such things! (except when they think no one's looking)
Aww, a poodle kept indoors when it's raining outside--that's a crime! Chagall always wants to go out and dance between the raindrops whenever he can. He thinks being kept indoors on a rainy day is a punishment. I told him once he learns to bathe and blow dry himself, he can go out in a hurricane if he wants.
He has a hooded yellow rain slicker which he's very good about wearing, but still those long poodle legs and paws get wet and muddy, he has boots too but I seldom put them on him. He'll jump in any puddle, pool, creek, go out to play or do his "business" in a downpour, but when he hears his bath water running he scoots away!
