I think that, first and foremost, you have to try to anticipate when this is going to happen and give him attention BEFORE he resorts to bad behavior. You don't want him to have a chance to practice bad behavior.

Also, you need to understand that for many pups (like many human kids), negative attention is better than no attention. He'd rather that you yell at him and carry him to "time out" than for you to sit there ignoring him. So, by letting him go that far and then giving him negative attention, you might be inadvertently rewarding the bad behavior.

Try to pay attention to him before this happens. You might also give him a stuffed kong or a nice chewy bone when you know you're not going to be giving him the attention he craves. Do it before he misbehaves.

Bare in mind that this is temporary. He will eventually outgrow this - especially if you are careful not to accidently reinforce it.
