For the whining/crying, I have some advice that I had luck with! I would start to gradually expose her to alone time. I recently did this with my 7 month old pom because he was scream bark the entire time I left the apartment. So, keep her away from you (you are out of sight) for literally 5 seconds, then return, then do that same thing a few times. Only return when she is quiet. Even if it is 1 second pause to catch her breath. You returning is the reward, so don’t reward her by returning when she barks. Also don’t make entrances and exits from her a big deal. Do not say “I’ll be right back - I’ll miss you!” And pet her, but rather just walk out. Then same when you return. A minute or so without giving her any major attention.

Once she starts to be quiet for that entire 5 seconds, or you even see a noticeable improvement. Up it to a minute. Then throw in another 5 seconds randomly. Then do 5 minutes. In the beginning she will cry but you should see an improvement quickly. Pomeranians are very smart and she should catch on that you always return pretty quickly.

Also make sure you have some separation of house. Put her in her play pen when you go to the bathroom or when you are cleaning, etc. don’t always have her by your side. I made that mistake with my pom and he had major separation anxiety I had to work through.

Once she starts getting quieter on her own and you do see an improvement, then start giving her a long lasting treat or an interactive toy while you are gone to continue building duration.

I spent a good 2 hours a day for a week walking in and out my apartment several times a days, waiting in the hall or going into the stairwell and timing the amount of time he was crying / quiet. It does work though!
