00:00This is Duke. He's 13 now.
00:03And last year, his back legs finally gave out on him.
00:07He just can't manage the walks he used to love anymore.
00:10So these days, he rides.
00:13We got him a little wagon, and he sits up in it, ears in the breeze, happy as anything.
00:18And this is Rex, the young one.
00:21Now Rex, he could run.
00:23He could chase every single squirrel in this whole park if he wanted to.
00:27He's got all the energy in the world.
00:30But he won't.
00:31Every walk, he stays right beside that wagon, step for step.
00:36He never runs ahead.
00:37He never wanders off.
00:40If Duke can't keep up on his own four legs anymore, then Rex slows right down to match him.
00:46And when we stop to rest, he rests his chin on the edge of the wagon, right next to his
00:51old friend.
00:52Nobody ever taught him to do that.
00:55He just decided, a long time ago, that they go together.
01:00Or they don't go at all.
