Aggression only towards me..

But if you are able to teach the dog this through non-corrective means, then more power to you. Depending on the temperament of the dog he may not respond to these methods and you may have to resort to correcting the dog.

Respectfully, in my own experience it doesn't work this way. I have used correction-based methods with an aggressive dog and seen the dog's behavior get much worse. Non-aversive techniques, on the other hand, brought immediate and dramatic improvement.

I never knew that they had a 2nd teething phase. I'll try only playing outdoors, she's always whining to go outside anyway.
 
She meets new people and dogs all the time. She goes to doggie daycare several times a month so she can interact with other dogs and people, she just loves to be around people and dogs as much as possible.

Well, we all had to learn[]
Take some of the good advice folks have given you, and I am sure your Sibe will do fine.

And, when she whines to go out, ignore her till she stops, then wait a few and take her out. []  Always remember who's training whom, and keep shifting that balance nicely until it's you training her, not vice versa. []
The second chewing phase occurs when the adolescent dog needs to set the adult teeth into the jawbone, and uses heavy chewing to do so.  So, you want to make sure you don't give the dog access to the dining room table legs when you aren't home!
BTW, even if you eventually decided that you needed an aversive to make the dog stop biting your pant legs, there are milder things to try.  Some dogs are discouraged if you dab a tiny bit of Vicks Vapo Rub on your leg.  I've been known to boil some cloves in water, strain the water into a spray bottle and use that on the fabric (never spray a dog with it).  Dogs hate the smell of cloves usually.  I might let the dog come up near my newly clove-sprayed pant leg, and watch for the ewwww reaction.  If he backs off, I might C/T and then take the dog to play in the yard.  So, he gets his play by NOT biting at you.

Agreed. Using corrective methods can make aggression worse in certain dogs. But much like each dog has a different temperament and personality, use whichever training method he/she responds best to. My dog responds well to a combination of positive reinforcement and corrective methods. I don't expect every dog to do the same.

This dog does not sound as severe as some of the other complaints here.  She sounds like she is a spoiled little gal.  She is having her cake and eating it too. 

My advice is to put her on a reward diet.  NOT so much cake and her behavior will improve toward the woman who owns her.  As the owner said, she is a model dog outside of the home.  She is simply getting rewarded for her naughty behaviors indoors.

As spiritdogs said, not playing with her in the house would be a good move.

No electronics are required for this dog.  She is still a puppy. Those nipping and taunting behaviors diminish even with little intervention.

At about 1 1/2 years, not 3....[] , with a few limits placed on her, she will be perfect.

Another little tidbit about Siberians is that they love attention and admiration above all else.  Using that idea when purging out the undesirable for you behaviors, may help a lot.

Well, I tried playing with her outside with different toys and she was completely uninterested in playing with me. She only wanted to eat grass, chase birds, dig, and roll around. So that wasn't working.
 
When she's biting my leg, I've been trying to talk to her like do you want a treat? or something to distract her and she will let go of my pants and I tell her to sit and then I give her a treat. That's been working to get her to let go of my pant leg but a couple minutes later she goes back to it. I'm going to keep this up and hopefully eventually she will get the hint to sit nicely to get my attention.
 
Someone said about her whining to go outside, she whines alot to try to get what she wants so what I have been doing lately is completely ignore her when she whines and then when she is quiet, give her what she wants, to go outside or food or whatever.
 
I try putting bitter apple spray on my pant legs but that only effects her when it is wet. Once it dries it doesn#%92t bother her and I have been trying this for so long I think it has just made her worse.
 
Someone said about hockey pads, lol, if I had them I would try it. I was trying to think of something to put on my legs that way it wouldn#%92t affect me when she bit me.
 
I#%92ve used a quirt bottle on her before but she just trys to bite the stream of water and lick it up.
 
Thank you everyone for all of the great advice, I#%92ll keep it up and just hope she gets better with time.

NO!

Sorry, respectfully, keeping this up is not going to have the desired effect. You are reinforcing her biting. She's going up to you and biting you so that she can get her attention and treat.

yup. She's teaching you that your cue to give her a treat is her biting your pants leg. Smart pup.
 
Would it be at all possible to not wear pants for a bit while you work on establishing a different behavior pattern? not go naked, but wear tights or shorts or something that doesn't have a flapping inviting piece of cloth to grab?
 
 
Here's how to teach a dog to let go of something on command: pop something into the dog's mouth you know the dog won't want to hold onto, and when the dog spits it out click (or say Yes or something, whatever the dog has been taught means "that's right") and treat. Repeat a few times. Then start saying "drop it" right before the dog spits out the thing.

I agree with fisher and mudpuppy.  Also, Bitter Apple, I am convinced, is something that most dogs seem to develop a taste for LOL.  Vicks is cheaper and it's marketed for another purpose. []
