Odin doesn't show it so much in the winter, but, in the summer, he gets very hot. If I walk him on a summer's day, when we get back home, he huffs and puff for a half hour. I really mean puffs. He blows out his cheeks and takes deep breaths to bring himself around. It is a little scary.
He seems to be in his element in the cold weather. He loves snow and could walk in the rain until he is soaked and it doesn't bother him.
