Phoenix is out on parole?
His owner just came over told us she was putting chicken wire on the top of the fence to try and keep Phoenix in, as per a suggestion from animal control. Guess they suggested chicken wire 'cause barbed wire is pretty much banned in residential areas.
Our across-the-street neighbor has seen Phoenix get out. He uses his doggy elbows to "climb" the horizontal supports on the fence to which the upright boards are nailed. When her dad built the fence he nailed the boards into the 2" portion of the 2x4, rather than the usual way of using the 4" portion, which gives Phoenix a lot more surface area to use to climb on. We're not "going there", though.
