OR: You can make your own "COOL MAT!"

I found using plain cotton (like your sheets) works best. Plaids and stripes also help when you're sewing the channels. Channels work best going the long way. (length not width) I have a serger but did not use one in making mine.
I also found, in the house, at least, that measuting it to fit inside your crate tray (taken OUT of the crate) makes it into a nice portable bed you can place anywhere.
If your dog sleeps IN his crate, make it smaller, so he can shove it aside if it's TOO COOL. Also, these granules are non-toxic and that's nicwe to know if you have a here-to-fore unbeknownst chewer.
