Hi Marlene,

Oh boy, you're not going to like this answer but YES he is acting out because of the new puppy! He's been "top dog" for the last 3 years and now you bring this adorable little baby puppy in, lavishing him with all sorts of oooh's and aaaah's and how-cutes!  Jujube is jealous and no way does he want to share you!!!  
He doesn't like the attention you are giving the puppy, and is acting out in a bad way so you will re focus your attention on HIM!! Even if it's bad. He'll do whatever he can to get you to notice him and take your eyes off the other little guy. "see mom, see what I did"!
The aggression, even if you think it's all for show, should NOT be tolerated one bit. Don't let him growl or put his paws on you challenging you. You are unknowingly sending him signals that he is the boss. Stop the behavior before it even starts.  If you see something that he did that was wrong, reprimand him immediately but don't play into the growling.
The first thing you should do is go buy some "bitter apple" spray at your local pet store and spray it on the things he's already chewed so he won't go back and finish the job.
LAVISH him with lots of attention to reassure him that he is still your number one boy. Set time aside that's just for the two of you to play. Give him lots of praise when he is doing nothing and being "good". He's just feeling nervous and unsure that this new puppy will be taking his place. If you give constant reassurance to Jujube and spend lots of time with him,(more than usual) he will eventually realize that this new little pest is no threat. It might take a while, and there still is the possibility that they might not ever get along, you have two male dominant breeds together and that is always a challenge.
Very best of luck to all of you!
