Interesting. Counterpoint: since the canines can't keep up with the humans, are they only used to start the hunt? How do they know where the humans are near the end?

Until the dog is fully domesticated (OK, I'll go home and await his return. He'll bring me meat!), I don't know how they could cooperate on a many-hour hunt like this.

I used to wonder the same about falconry until I met a hawkmaster. The animals don't take prey far away where they'd be hard to find; they hover or perch near the humans in open fields, where they are trivial to find.

I also wondered why they don't just eat the prey. It's because that involves lots of effort; they know a human will shortly arrive with tasty food that isn't wrapped in tough fur. Basically, they trade a package of hamburger for a Big Mac.
