When I meet a person and somehow learn they don’t like puppy breath, I have an innate level of distrust for them. This is most likely a matter of perspective, as my job entails being exposed to a much wider variety of canine breath than the average person. I get little puppies with the milky sour smell of puppy breath as they grunt in my hands during an exam.
