I was wondering if any of your humans do this? Lately specially on gloomy days Mom leans into me, puts her face right up againts me. Then her just inhales deeply, sometimes just once, sometimes for several minutes. When she's done she always thanks me. Odd I think but, it does seem to please her. She tells me the only thing that remotely compares to a smell as pleasing as mine is puppy breath! Odd, odd, odd!
