I'd had the old beanbag for all my dogs over the last so many years. When I started out on my own, it was the only piece of furniture in my apartment. Until we brought Murphy home, nobody had ever felt the need to pee in it, and the poor bag never had an inner lining to begin with. It's time to toast to the Era of the BeanBag and remember it's best and most memorable nights, but meanwhile, Moose demands her window seat. The only money we spent on this project was a 100% waterproof toddler mattress from Walmart for $37, which I felt was a stroke of genius. The wood was all scrap we'd had lying around for ages, and after a quick stain, there's nothing our little Peabody can do to hurt it. We threw in an old sheet and doubled over an old blanket that smells like us. It's not perfect, but we did it with no plan in about 2 hours. The dogs are happy, so we're happy too!
