My cousin Christy lives next door, and her family used to have a beautiful Bernese Mountain Dog named Joey. He predicted rain too. Always a calm and sweet dog, he would start acting spooked and hyper before a storm. He would howl too. And then when the storm started... he went psychotic! He leaped right through their screen door twice, and once he came through a screen in our window! What a surprise when we came home and found my dad laughing in his wheelchair, unable to do anything as Joey made himself at home.
