Some pet gates take just a few seconds to install, and others require a little more effort. Each pet gate is slightly different, but most can be installed by expanding the width of the gate to the width of your wall and tightening the tension knobs. If you want to save your walls from damage or frequently move your gate from room to room, we recommend getting a pressure-mounted dog gate or a freestanding dog gate. The pressure-mounted gate means no screws, no damage to the wall and it’s easy to install. This pet gate style is much easier to use than others because of its mobility, and it can make containing your pup a simple task.
