I decided to do a net search on my question. Odors of any kind are volatilized molecules that are carried in the air. It got weird pretty quick in that nearly anything is not just a liquid or a solid. When our dog smells us, it's our own volatized molecules that they perceive and identify as unique to us. I did not see any answer to whether some conditions enhance the detection of odors, but it may have been there. It distracted me to think nearly everything around me is emitting those molecules. I guess I shouldn't have been caught off guard so much. Everyone likes a 'new car' smell, don't they?
