Snoopy isn't bothered by either lightning or thunder. She sleeps right through them. BUT she will not go outside in the rain. She does not like the rain hitting her eyes/face. She also cowers if caught in it or just refuses to go out if it is already raining. So when I know a storm is rolling in, we try to beat it with a potty trip. It makes me wonder why some dogs are bothered by storms and others are not??
