When ever Jesse and I hug or kiss each other you can guarantee Cooper will come running. He jumps against our legs and bumps them hard with his front paws while barking at us. He's really funny about it. He'll drop everything to come get us to stop.
Sometimes we pick him up and put him in the middle of our hug while we kiss again. He barks and squirms around until we put him down.
I wonder what he thinks is going on when we hug. Does he think we're challenging each other? Does he feel like there is some kind of conflict? This would be a really good question to ask the dog whisperer. I'll bet he would know.
