We have a chain link fenced in backyard right now and it's about four maybe five feet. It's pretty small but we're military so we when move again we're either going to buy a house or rent one with a bigger yard. But they do fine with the small back yard. I think they enjoy being able to look out and see people walking in the neighborhood and whatnot. And we've got friends up here with huge backyards that we take them to as often as possible.
