It's always a little chilly in San Francisco so I am always on the search for products to keep our Chihuahua warm. I came across this heat pad that you can throw in the microwave and thought I'd share. This is also the cheapest I have seen them sell it.

You can buy the cover for it seperately.
I know for most of you guys it's hot out there but I thought it may be interesting anyways...
