Dog scared me out of my pants

My son loves looking out of our window, and he can see little dog that lives next door almost every day. Today my son came to see me at the computer and he was naked, he is almost 3 but it is hard to understand him sometimes, so I didn't understand why he was naked. So we started talking and finally I got out of him that the little doggy next door scared him out of his pants, it was so hilarious, I couldn't stop laughing and he had so much fun with that story too!!!!
