I also don't have a yard but tie-outs are strictly forbidden in my city. Not that I would use it with Payson because I'm scared he would hurt himself (especially with his penchant for tangling himself in even 6 ft leashes). Unfortunately, Payson abhors going for walks around my neighborhood so I have to find creative means to give him exercised, including obstacle courses around the house and over the sofa, or else drive him to a different location.

By the way, have you ever considered an invisible fence?
