Tanq, our French bulldog, is tumbling with a weimaraner cross and an Aussie cattle dog puppy. In the next run, a boxer and a lab run from one end to the next, leaping and dancing together. Old and young, small and large, shy and bold, they're out there together. When one tires or gets hurt, the others check in then let her rest. When outsiders arrive, the welcoming committee greets, introduces, then incorporates him into the play. If one misbehaves, the others let him know he's out of line, and then invite him back into the fold.
The Kingdom of God isn't fluffy clouds or an endless harp concert, to be sure. But maybe it's a neighborhood dog park, right around the corner from where you live.
