Uh, the "vixen" is a boy. That's the only sweater I have, and I keep the temperature kind of low during the day, so the two old dogs get sweaters. Sammy chewed through his yesterday, but he's a heat box anyway so he doesn't need one.
Ooops, sorry, no offense intended! That can be a unisex sweater---Tarzan for boys, vixen for girls. You are such a good mommy!
