It's big and roomy.  My Yorkie has too much freedom in it while potty training.  But for play time with her lab-pooddle mix cousin, they have plenty of room.  Toys, blankets and occasional ball all fit fine.  When company is gone, the "condo" goes neatly back into the garage.  I've found it very useful for when family is outside, I put her in it and don't have to worry.  Great for us.
