My baby pup is not here yet so that means I haven't tried it yet. But I do have it sitting in my room. I took it out of the bag and was able to put it back. . . but was unable to zip it back up. Like you have mention the only thing that I was not happy about was with the height of it. I thought it was going to be much taller. . . since your yorkies look fine in their I'm guessing mines will be fine too. I LOVE HOW IT HAS THE TOP ZIP! You dont' have to worry about the baby jumping out while you were gone. hehe. That what total won me over. . because play pen they can get smart and learn how to jump out. Same with door fence. But with a Zip. . . no way! hehehe. We'll I'm excited to use mines and since it seems like all your pups are doing great in it I'm sure mines will too!
