receiving non-sexual cleaning type touch from another human (think hair brushing, hair cut, skin care or even someone applying the lint roller to your shirt) leads to huge increases in oxytocin.
The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

when humans stroke dogs, or brush their dogs or stroke cats or brush their cats, et cetera, that is a form of human to animal allogrooming. And it's one in which both the pet and the human receive huge increases in oxytocin and other related neurochemicals that make us feel bonded.
It's known to increase levels of oxytocin, a kind of hormone slash neurotransmitter. That is known to evoke feelings of bond.
if you look at the literature on allogrooming, what you find is that when humans groom one another, the increases in oxytocin that are experienced are at least on par with and in fact, more often, more dramatic in response to allogrooming than in response to other forms of touch.
