5. “I Miss You the Moment You Leave”
Have you ever wondered if your dog actually notices when you are gone? They do — every second. Dogs experience time partly through scent. When you leave, your smell starts to fade slowly throughout the day.
To your dog, this fading scent is like a clock counting down. When the smell becomes faint, your dog knows you have been gone a long time. When it grows stronger near the door, you are coming home. This is why dogs often wait at the door at the same time every day. They are smelling you arrive.
