We travel with our 2 small dogs in our travel trailer which at times they feel very cooped up. Having an exercise pen that is so compact and easy to unfold is a dream come true......for them. We connected several of the pens together to give them a lot of space to run and play without having a leash restriction. The strong panels allows you to shape your play area anyway you like. The easy to adjust clasps are great too. It gives us peace of mind knowing our dogs can not escape in this safe and secure play area.
