jealousy

Question
First of all, thank you for all you do for the love of dogs.
I have a 3 yr old dachsund/beagle mix named Bandit. We have a strong bond. He used to go everywhere with me (as I dont work)
car rides running errands...visiting my mom... Then I agreed to take my nieces 7 yr old min pin Wayne ... his personality is lovey dovey and he responds well so no problem there.
Bandit likes Wayne as far as when its time to run around in the backyard and play and bark.. but Bandit prefers people.
My niece joked that Bandit thinks he's a human cuz he will even sit and look at me and my hubby while we're talking and tilt his head.  Let him outside, and he sits by the door waiting to be back in.. only nowaday with Wayne he stays out longer..anyway, he gets jealous like if wayne comes to me,
bandit will try to start playing with me or play bark to get my attention and be persistant.  He isn't aggressive with wayne tho..he just doesn't want to let wayne get the attention.. he sniffs waynes privates a lot i guess outo f curiousity.. both are neutered.. bandit just can be nervous/jealous at times. Since I love him, I wonder what I need to do so that he feels more secure about himself?
I've tried to give you as much info as i can think of
thanks  oh also i love wayne he is a cutie but i dont feel a bond there like bandit.  also i dont use a clicker...i'm more into voice inflection and hand signals..for some reason it seems like dogs learn so fast when u make up your own hand signals!

Answer
No one is going to force you to use a clicker, LOL, but the principles of training are the same when you use your voice as a marker.  Your inflection when you say "yes" or "good dog" should be constant, so the dog learns to recognize that as a signal that he has done the right thing.  The reason they learn hand signals so quickly is that body language is really their native language!  When you have a multiple dog household, generally the dogs decide amongst themselves who is top dog.  The important thing in terms of having your dogs be secure and confident is that you are in charge in the household (in a nice way, of course), and that they understand what you expect of each of them.  That's where training comes in.  Both dogs should defer to you and respond to your cues, then they will feel that there is a leader already, and they don't have to apply for the job. Don't intervene in their tiffs as long as they aren't doing any damage to one another and one dog isn't being hounded obsessively, etc.  But DO set aside separate training times, and separate play times for each dog to get your undivided attention.
