I really like this lightweight “boundary”. I’m using it to block off night access to part of the living area. My dog is older and relaxed, and it works perfectly. Not so sure if it would be good with a pup that likes to chew, or a very active dog. In that case, I would opt for something more sturdy. But as I said, it is perfect for a boundary that you want to move often. It’s thin, lightweight and clear.
