This is the newly-bought dog bed for my buddy. It is a round and foldable one, which keeps him warm in cool days. I was told that this type of dog bed is orthopedic dog bed, and it is good for tiny dog, because it provides more supportive cushioning to dog's bones. Bought it from crazysales and 40% off. Great deal. Choosing dog beds is sometimes tricky. You also should factor in her personality, agility, health issues and even the available space in your house, although the most obvious factor is the right size.
