Maybe a shaker would help. My Lulu’s the same, her trainer made a shaker. An empty water bottle and mini size stones in it. Constant positive reinforcement is needed at the beginning. We actually practiced and had my son approach our front door and before she barks we redirect her attention by shaking the bottle. This snaps them out of their current state. Shakers are good for training, I dont like her jumping up and down during dinners asking for food- so I used the shaker to tell her its not ok- with a firm no ofcourse. Then after awhile- I just raise my finger with a firm No.. we dont need the shaker anymore. It doesnt work for all dogs... but I hope this helps
