Two tennis balls

I always take Marley's purple ball when I think we might be heading to the dog run. I never know if there will be other dogs there or if it's going to be just us. The park workers sometimes leave tennis balls for the dogs to play with, but sometimes they're so ratty that the dogs don't want to pick them up or there might not be anything. If I take Marley's ball, at least he'll have something to run after.

If it's just Marley and me at the dog run, or at the ball field, he has no problem chasing after his ball. But if there are other dogs there, he prefers to chase the dogs. If the other dog has a ball, Marley would rather grab that ball than fetch his own. If I throw Marley's ball, the other dog is likely to go chase it. I've spent a lot of time throwing Marley's ball to other dogs. There's just something about the other guy's stuff.

We were at the dog run over the weekend and I saw something new. There was a larger dog running around with a tennis ball in her mouth. Her master threw another tennis ball and she grabbed the second ball. She ran around the dog run with two tennis balls in her mouth. Normally, a dog drops the first ball and pick up the second ball or nudge the second ball and keep the first ball in its mouth.

I often see what looks like dog A.D.D. If you have a toy and roll it near a similar toy, the dog will pick up the first, hold it for a few seconds, put it down, then go to the second, pick it up, hold it for a few seconds, then go back to the first. Repeat a few times. The dog would grab both, if it could. The dog has to choose, but is unable to.
