I had never thought about it until we'd watched him. But, I had thought about a raincoat for him. Jet had one that he liked.
I've thought about your girls and theirs.
However, it's doubtful that 'rainy season' will start for a while, yet - wouldn't I love to be wrong about that!! - so I'm holding off. If I wait until the time is closer, I can fit him better, since I'm assuming that he's got a bit of growing left to do.
I think that he'll look fetching in a nice little coat, and it will keep everything in the house dryer and cleaner. (like our recliners!) There's nothing like a double coated dog to smell like, well, a wet dog, lol!
