Need serious help with housebreaking an 8 week old Golden retriever/black lab mix

[jesse's mommy]

Here is what I mean about wanting to strangle her sometimes -- we came home today and found that she put a hole in the comforter that is in our spare bedroom and pulled out the stuffing! She sleeps on this bed while we aren't here and looks out the window and watches everything. It's basically her bedroom! But I did spend a lot of money on this particular comforter because I like the bamboo pattern on it, so I'm bummed. It's my fault because I should have put an old blanket on top of the comforter. I'll just get the needle and thread out and know for next time! My little angel!
