Felix came to our place one evening and we played in the pasture with Jack and Theo. The two shepherds were pretty much obsessed with the ball. Most shepherds have a bit of Obsessive Compulsive Disorder and both Theo and Jack are fairly far up in the spectrum. Felix is a dog and he prefers dog-on-dog play: you-chase-me, I'll-chase-you. Felix knew that Theo was beyond hope, but he tried his best to get Jack to play. Everyone got a good run anyway.
This afternoon I took Jack to meet Felix on his own turf, with no tennis balls. Jack found the biggest stick he could find, must have been 10-12' long, and proceeded to carry it around. There was a wading pool too, and he laid down in that, of course. Later he found a rock. Jesus.
Again, Felix tried to get Jack to play dog-on-dog, but Jack didn't really understand. Jack is learning, I think. I've seen him almost engage in play with Maya and TJ, and Felix got him going occasionally. Although Jack didn't understand, he did have a good time. I promised Felix I'd bring a real dog next time.
