Robin tears up the sheet in her crate, which I kind of expected...
But she does the sheet/blanket nibbling thing in our bed, too, and she seems to love tags on things like the shower curtain. She's about 18mos old, and it does seem to have lessened lately. I've got one set of sheets with ratty corners because she just corn cobs the hell out of them.
Sheesh. With dogs and kids, you can't have anything nice!!
