My dog owns me

I have an 11 month old Boston Terrier/Beagle which we have had for 8 months. He is neutered. He shows no food aggression as I can take his food away at anytime. He does not go to his food unless given permission. He learned to sit quickly but doesn’t always do it on command. My problem is he wants constant attention from me. I take him out first thing in the morning. Then he goes to his crate until everyone goes off to work. Then I take him out about 8 AM. I feed him, play with him, and rub his belly. After play I take him out again. Then about 9:45 I go to do work in my office which opens to the kitchen. The only thing between us is a metal baby gate. My desk chair is about 2 feet from the gate. Even though Mitchell might take his chew rope or bone and lay to chew on it across the kitchen from where I am he will not let me leave. When I get up he jumps on me and mouths me. I say mouth rather than bites because although it hurts he doesn’t leave any marks. He pulls on my clothes and often tears them. Then he stands at the gate and barks. I have tried treats. He started barking, stopping when I told him to be quiet, then barking again after getting his treat. It soon became quite a game with him. Ignoring it does produce some results but not for 10 or 15 minutes of non stop barking. I tried spraying with water and then lemon juice but he loves it and again it is a game. I bought a sonic bark collar so now I have a barking dog and a sonic sound. I am worried about his mouthing when he doesn’t get his way and his barking is hard to take. I have yelped since we got him when he moths but he doesn’t seem to care. When we play and he mouths, I tall him to get his toy and he will but I don’t know how to get out of the kitchen without having my clothes torn and his mouthing. I realize he is an adolescent but I don’t want this behavior to esculate. Hr doesn’t behave like this with my adult sons.
