It's called Casual Canine Snowsuit and I got a Large since she has a deep chest. Normally, a large is too long but it has about a 3-inch slit in the back - just perfect for her tail to slide in and stand at attention :). I waited for a sale to get it.
This is very interesting, Sinbaje. I have also read that because of the way water is recycled in reservoirs (in the UK, I don't know of other countries) such residues are causing hormonal problems in humans!
