My dogs wouldn't look guilty if someone gave them a treat after I'd told them not to eat it. Happens all the time, I say no and DH caves in. So in that case, yes I'd probably be reading their reaction to my reaction when I was told they'd been naughty. I suspect they'd be acting differently if they actually had done something they knew was wrong.owners were asked to leave the room after ordering their dogs not to eat a tasty treat. While the owner was away, Horowitz gave some of the dogs this forbidden treat before asking the owners back into the room.
