Sounds like Benji is a tad bit jealous and wants some affection too
. But in all seriousness I think this is somewhat normal dog behavior. My bulldog wants hugs/kisses if I hug/kiss my son and my yorkie barks if my hubby gives me kisses/hugs. If the behavior gets to be too annoying you can curb it by saying a brisk "No" or making a "tsk" noise. I'm sure others will be on later to offer more advice
