How much space?

Q: Re: Tearing up loft We tried expanding his space a couple of times. Each time he's peed on the play area floor. In your video, it states that if they don't consistently return to the palace to potty, they need more time in phase 1. I wrote you about this a couple of days ago and you mentioned that maybe the space was too large. Do you have any images of examples for the size of the initial play area? The only images I have to go one are the fully built out pens from the videos. Sorry, this is my first puppy so I'm new to the process. Just trying to find my way.

A: What apparatus are you using to expand his space? If it is an exercise pen you do not need to use all the panels, for example you could only use three which would give a 2'x2' addition.
