Okay the last few days Aisha has started growling at everyone. I'm not sure why (trying to initiate play?) For example, about 10 minutes ago I walked out of my bedroom to grab my sons sippy, and she looked at me and started growling- just stood their growling, even as I walked away. I know puppies aren't aggressive, I've read it a million times on here. What can I do to stop this? She growls at our feet, when we walk, and when we enter a room, if we are holding anything in our hands.
On the training front we socialize Aisha daily, we practice NILIF (I've only been doing it with her food, should I do it with her toys too?), car rides, stores, outside adventures on the deck (sill muddy in my yard), and I carry her with me when I walk to the mailbox (I'm still waiting for her final vaccination before I let her walk in high traffic areas). She doesn't however have many dogs to play with, and we had to postpone puppy classes for personal reasons (Going to attempt to get her in hopefully in May when they start up again- with basic training).
I just don't know if we are doing something wrong or not enough of something. I have a very busy schedule with her and my son. We never hit her, we never yell at her, and we just ignore her when she growls/ barks- not working so far. MIL even tried the water bottle sprayer, but it makes Aisha growl/ bark more, shaking cans also makes her bark/ growl more. We do also play with her constantly and we do training 3 times a day for 15 minutes (still working on leave it, sit and not to jump up- that one is failing miserably). We are trying our best to keep her occupied and content.
I'm going to have to assume she's trying to play with us, but I would rather she not growl to initiate it, if thats what she's doing. How do we approach this?
Ah the joys of puppies...I know it won't last and it will be rewarding in the end, but goodness can it be tiring and frustrating!!! 
Oh, and I have no clue obviously how to teach her a "quiet" command.... if you couldn't already tell. How do I do that?
When I can't watch Aisha she is either attached at my waist or DH waist with a leash (which has oddly enough made her great on a leash), or she is in her crate. I thought maybe I was giving her too much freedom with letting her roam around dining room, kitchen and living room. So we have been doing this the last 2 weeks- haven't really noticed a huge difference in her- she is VERY confident and some what pushy puppy.
I'm wondering if she just isn't quite tired enough, I know Pomeranian's can go through huge bursts of energy throughout the day, maybe I'm just not doing enough.
Anyone have any suggestions on that front?
I still don't have a backyard- and I won't until May (my fence and Sod gets put in). But I do have a rather big deck that I have been bringing her out to play on.
Sorry for the long/ scrambled post its been a really really long day, and I'm completely worn out. I'm just glad its bed time for my son right now lol.
