Keoki and Jazz have similar behavior.
He's a gobbler, she's a picker. He eats his food and runs to stand by just in case she lets him get her food. She growls if he gets too close, and once she is done she lets him move in to lick the bowl.
The behaviorist described his behavior as a form of silent bullying. What we do now is feed them at the same time, as always, but we do not let him go anywhere near her when he is finished. We started by physically restraining him, ie holding, and moved to simply standing a few feet away from Jazz and not letting him go near her {by just walking in whatever direction blocks his path. }
The whole process only took maybe two weeks. Now he eats and goes trotting around the house, minding his own business, until she finishes. She eats in peace, and he is allowed to go lick her bowl when she leaves.
IF she opts not to eat at that time {I give her about five minutes}, then I remove her food and she isn't fed again until the next meal. I have to control eating times simply because of our schedule, and I don't issues of feeding her later and having the other two dogs getting all worked up for food.
Anyway, that's what we did/do…...FWIW.
