That is amazing, I didn't know they could work that cold. -22 is amazing also. The coldest temp I've ever been out in was -12, but that was on top of a mountain and we were full-suit and face mask for skiing. Your little dogs must be doing their business real quick. My skinny whippet needs a coat in the cold weather and doesn't waste any time out there, but it's a relatively balmy 6-degrees here this AM.
