I'm looking into getting either a pet bed warmer or a pet bed thats heated for the winter. I was wondering if anyone else has one, or has used one. I want to get one that's safe and works well.

. I've seen so many, and just wanted to know what other owners have used / tried. I like the microwave pad, just because there's no cord to worry about being chewed on by a pup. Constant heat would be great too, then I could be lazy and not have to make sure the pads warmed.

Suggestions are needed here! My pup hates the cold!
