Great pet bed but it is bigger than I thought it would be.  it took my dogs a little be of time to use them but they both really like them.  They are fluffy and come in great colors.  I bought two of the extra small (I have two chihuahua mixes Hamlet 6lbs and Romeo 21lbs)  it is plenty big for both, in fact I could have probably just purchased one if they liked to lay with each other.
