In the summer, Oatmeal is miserable in our Tennessee heat. He sheds and pants and is generally a very unhappy camper. Meanwhile, Emmy is happy and comfortable as all get-out.
In the winter, the tides change. Emmy gets a downy undercoat but it's not particularly thick. My little girl gets all cold and shivery so I bought her a jacket. If you'll allow me to anthropomorphise my dog, I'd say she's incredibly embarrassed to be seen in the little pink number I bought but she tolerates it like the good little girl she is. I love this picture where she's looking at Oatmeal thinking, "Why doesn't he have to wear this dumb thing."
