I’ve never owned a dog but looked after some and became good friends with others. Their behavior always fascinated me. In my youth I read Konrad Lorenz’ “King Solomon’s Ring” where he dealt with some somewhat mysterious dog interactions with humans.
I currently have on my reading list Rupert Sheldrake’s “Dogs That Know When Their Owners are Coming Home”. The thesis is that there might be some sort of telepathy between dogs and humans. I’ve heard some interesting anecdotes from dog owners that do make me wonder.
Our dogs always started to bark excitedly before my dad's car even pulled into the driveway. They just sensed his arrival.
Dogs seem to get excited whenever I walk past them. I don't know what they pick up. (Hopefully not any B.O.!) I like dogs, but don't keep any as pets.
