First, 30 degrees is actually quite comfortable after a week near zero. I was just out with the dog for 5 minutes, wearing a light fleece sweater, and out of the wind 30 degrees is nothing. And I suspect most of the Californians that spend their vacations skiing in Montana know it, too.
Also, 13 year old dogs are not real enthusiastic about the "good dog" reward. It's not that it doesn't mean anything to them, it's just they've so heard it before. The hairydale at two years old thinks that good dog is the greatest reward that could possibly be bestowed upon her.
The basenji at 13 thinks the hairydale is giving it away, and as far as she is concerned, "good dog" is a compliment like "nice tie" from that guy in the next cubicle; not bad, but not anything requiring a celebration.
The airedale lives with us; the basenji thinks we live together in our house. "Now open the damn door, I'm from Africa, I don't have a fleece sweater, and 30 degrees is still frigging cold, even if your not as old as I am!"
