The extra space in the puppy pen allowed for an extra dog bed. Since the six puppies alone can take up one of the beds, putting one in for mom to use was the idea. It looks like no matter the number of beds, mommy has shown them all it’s hers. You see, I had just taken Barbie out of the pen for a potty break and yes, she was in one of the doggy beds. Look where all of the puppies setup nap time! Too funny!
