Hi! Kiwi and I live in California where 50 degrees is a cold day. She has sweaters, but really nothing else to wear. We are going to Colorado over Christmas and boy it looks like it is going to be cold! Could any of the cold-weather Yorkies give us some tips on what to wear? I think she needs a coat, but does she need boots/shoes? Also, is it a good idea to layer? I don't think she is going to be outside a lot, but she will be out some. Thanks in advance!
