My friend Ashley recently told me about a cool site for dog beds that I hadn't heard about. It's called PawDigs, and while some of their beds are a little pricey, they're definitely worth it.
Beds by Madison Avenue Mutts
They carry a variety of beds from two of my favorite companies—Harry Barker and Madison Avenue Mutts. You can choose beds by size, and they even carry orthopedic pads, mats for crates or traveling, and variety of eco-friendly designs.
Here's their site if you want to take a look! http://www.pawdigs.com/
