Thank you everyone for the encouragement!
I've started the sweater, my lil' man is worth it.
Wanda, the Phantom sounds like a great pooch! Give her a scritch for me. It doesn't get that cold here either, but the past couple of years or so have Punkin really uncomfortable when it gets below 40. Rather than buy another sweater, I figured I'd make one for him. You're absolutely right, they are great companions!
