What was the earliest known relationship between early humans and wolves/dogs, and what did they both stand to gain from the relationship?

I’m not gonna do the fact-finding for you, but it was at least 10,000 years ago.

The branching of wolves and dogs started with some wolves that weren’t as scared of humans as the other ones were. 

The brave ones lived closer to humans. They ate human garbage (bones and food scraps). They began to associate humans with easy food.

Humans who weren’t scared of the wolves tolerated them hanging around because they didn’t bother them. They cleaned up their messes, and kept other, meaner predators away. 

Over time these benefits became more and more pronounced and humans actively fed wolves in order to keep them around as protectors. Then companions. And hunting partners. And utility animals. 

The friendlier and more cooperative wolves got more special treatment, and over generations they were bred into primitive dogs. Once the dog-human Bond was well established, selective breeding to achieve certain results began, and the oldest breeds were born.
