I know this sounds weird or maybe even silly but my female
chihuahua is only 3lbs. And the other one is about 7lbs. They get
so cold in the winter. We already had snow flurries yesterday
(luckily it didn't stick) and they just shakes so much even in the
house. My littler one is so cold.
Wal-mart has sweaters on sale for 5.00 each that I'm pretty sure
will fit both of them. Luckily my male chi already has clothes so
he is warm while my 2 little ones shiver.
Maybe even used sweaters would work? they are just so cold!
