Allison makes a burrow bed that allows your chin to burrow underneath a flap of fleece and sleep on a padded fleece pillow. I believe her website is camphorchins.com if you'd like to check it out.
Both my chins sleep under their fleece liners ALL THE TIME. I get really worried a lot of times because it has to be hot under there but its like I can't stop them. If anyone has ideas on how to keep the fleece liner down so they can't get under it, that'd be great!
They might like one of those round hanging fleece house things...I'm not sure what they're called, I think a bungalow or something. It's just got a hole or two for them to crawl in through and then they are surrounded by fleece
