Domestication actually is an evolutionary process that does not take place in the lifetime of one animal or of group of animals. Coyotes can be socialized to people but are un-predictable as pets since they are inherently wild animals.
I saw a tv program where researchers took wolf pups and dog pups at the same, very young age and each group - wolf pups as one and dog pups as the other into home situations with people. It was arranged exactly the same, in terms of living arrangement, exposure to environment and various other things, way of handling etc. The wolf pups at a young age showed much more competitive and food protecting behaviors, and as they became more co-ordinated, were climbing walls and furniture and easily aroused, hard to re-direct, extremely "hyper" and hypervigilant and by 6 months were un-controllable in a human home. They were just acting like wolves.
Researchers also had a test where they brought a wolf pup and a dog pup, one at a time, into a room where I think there was hidden food under a dish or a cone, or something like that. There was a vast difference between how the wolf puppies responded and how the dog pups did. The wolf babies were not engaged in the activity in the same way, did not seem to learn from the pointing that the humans did, to help the puppies find the food. Dogs do understand and respond to human pointing.
