I suspect it’s mutual. It allows things like fetching downed small prey, like certain modern hunting dogs are trained to do, so fetching spears and whatnot isn’t too far of a stretch.
Meanwhile, it lets dogs exercise, play, and otherwise flex their instincts. Not to mention that they’re perception of humans as pack leaders and family inclines then to like making they’re person happy. Working dogs are seen clearly enjoying their work and/or the rewards (emotional and otherwise) from their humans.
