I thought I'd share this good idea we came up with. My husband spends lots of time in our two car garage with the door open. It's his "man lounge"! Our pups like to be out there with him. We put some eye bolts in the wood at each side of the garage door opening and attached one end of our x-pen to both sides so that the fencing expands the width of the opening. Now the dogs can be out there with their dad but can't get out of the garage!
