All of mine wear sweaters as they get cold easily especially since small dogs loose their body heat extremely fast. And I love dressing mine up in the winter!!!
I get mine from
www.barkindogclothes.com. You get to pick the fabric and they have different desings as well. Shipping is free in the US and the sweaters are at such a great price and Rena does such a great job making them and you get them really fast. I just ordered a really cute hoodie for my Destiny and it cost me only $9.
