The exercise pen is two feet high and Loki is maybe a foot tall now. We did buy a top for it, but had kept it half open. We figured that he is still a puppy and couldn't climb out. We planned on closing the top when he got bigger. Luckily, Yun forgot to close the balcony door that morning, so Loki was able to go out there to pee and poop, both of which he did in the correct spot. Amazing!
What happened? Did you put Loki in his pen this morning?
Yes. I definitely did.
Did you forget to close the balcony door?
Oh, maybe I might have forgotten to do that.
The door of the pen is still locked.
Oh, I guess Loki must have climbed out.
Well, now we definitely keep the top closed when we leave him unattended.
Never underestimate a Shiba!
