Okay, so Penelope is chewing up a storm. In fact, I had to put her in a kennel to write this. She has already ruined a rug with me watching her, telling her no, and giving her an actual chew toy to try to teach her what is appropriate chewing. It doesn't work. She goes right back to it, material and threads get caught in her teeth and I have to sit there and pick it all out. She just barks back at me. I'm doing what everyone says to do and it just gets worse. If the bitter apple I'm going to pick up tonight doesn't work, I have no idea what I'll do to help correct this behavior. What am I doing wrong?
