Coyotes are better able to survive in the more arid regions. They can actively hunt smaller game, not just for themselves, but also their master. They can assist with larger game. And capable of providing protection.Possible, but not necessary. Native Americans already had dogs, why would they need to tame coyotes?
They could domesticate fish like the chinese did, or a lizard species, I know the Common Chuckwalla and Iguanas are plant-eating, I think perhaps with a POD about 75,000 years ago with the black bear growing cellulose-digesting bacteria in their digestive system you could have them slowly lose some of their edge, moving towards an entirely herbivorous lifestyle. Megafauna would work as well, don't just considered living species. Or you could have fauna from the old world come over with the first humans.
