My poor little Peanut's hair is sort short and fine that she gets really cold in the winter. If it's too cold, she will put on the brakes and flat out refuse to go outside, and that's a problem. Solution: sweater (aka: prosthetic fur).
Here she is modeling her ugly Christmas sweater. Not my first choice, but options were limited and she needed a fur substitute right away.
As soon I was able, I custom made this lovely little sweater for her. She's always quite excited to see it on cold days.
