I am on the hunt for a decent, but inexpensive dog bed for my Tilly. It seems as though every bed I end up buying turns into garbage! The last bed we got, I spent $50 on and it was made up egg crate on the inside, which quickly flatten out. (Tilly is a whooping 63 pounds!!!) and the top pf it just got shredded from her trying to "fluff" it everytime she lays down. Any suggestions? I need something that can be stuck in the washing machine as I wash all the dog beds weekly.
