I had to go home my first weekend at college, and the second as well, because my dog would not eat. He spent all of his time on my bed. Finally he learned that I would come back. Sometimes and got over it.
When my oldest daughter came home on breaks our dog would immediately run to his food bowl and bark to remind her that it was her job to feed him. Didn’t matter what time of day she came home, he just wanted to let her know her place. It had been her job in high school years.
