That's so sad. I'm so very sorry for your loss of sweet little Rain. My heart has almost stopped on occasion with loud thunder claps... I can't imagine being a little Yorkie and not knowing what thunder is to come that close to it. Maybe it had something to do with the excess electrical charges in the air... I know I was experiencing some very weird sensations those couple times it happened to me. Maybe you should keep one of his pups when they arrive.
