Hmmm ..... I have some advice for you and some things that you might want to look at when you interact with your pup in the future

First of all with the barking and growling at the office and at your Moms house
This sounds more like a dog who is insecure than a truly aggressive dog
But an insecure dog will snap at people out of fear too so this behavior must be stopped also
when you go to strange places bring lots of treats with you and tell your coworkers and your boss when ever you come to say hello to the puppy ... give her a treat
... pretty soon shell love strangers

1. Reinforcements .... it depends on the kind of behavior youre reinforcing
Sitting and tricks? Yes you alwways want to reinforce those at every chance you get
Curtailing Bad behavior though .... like biting ansd jumping up you say No!!! and curtail any further interaction
Barking youo say No Bark! and then Good boy! or Good Girl when they stop
So reinforcement will depend on what you are training them to do

2. The barking ... like I said before this is coming from her insecurity
The more you expose her to new things and new people and socialize her well the less this will happen
