<human>: Condense the text into a few key points

I had purchased a nice memory foam bed in preparation for our puppy. Once she'd made good progress with house training, we introduced it to her crate so it would be softer for her at night than towels. She ripped a nice big hole in the side of it and made confetti of the foam shortly thereafter, so we threw it away and went back to towels, which she continued to dig at and rip with her teeth.

That was months ago. I just today tried introducing a new, more rug-like bed to her crate. I first supervised her with it this morning with the crate open, discouraging her when she dug and nipped at it and click-and-treat for sitting/laying on it nicely. That seemed to go well, so I crated her just long enough for me to take a shower. She'd ripped the edging off one side.

I just want her crate to be more comfortable for her, but of course she doesn't understand this... I don't want to leave the hard bottom of the crate bare, but I don't want to continue reinforcing the destructive behavior by giving her towels/beds.

I want her to eventually have a healthy relationship with soft things... What can we do about this?
<bot>: Pup keeps destroying her bedding, but we don't want to leave her in a hard crate... Please help!
