Combine the dislike of being cold and cleverness, and you end up with one like Dinky. He walks like a champ unless the weather is pretty cold. Then he wants to be carried and be tucked into our jackets! I make him sweaters out of my DH's socks, and that helps, but somedays he gets carried until we turn around to go home. At that point, he scurries home as fast as he can. I guess it's okay because we don't mind.
He also refuses to walk if he needs a nap. I can't blame him for that. I'm the same way.
