How to fix the incorrect sitting posture?Do you have access to a balcony where you can set up a potty station (think fake grass on a platform over a grate with a puppy pad underneath to catch the urine and can be easily changed/cleaned up) or a walk-in shower you are comfortable training her to use as a wee station? I ask because we were literally only a 20 minute potty timer until Molly was like 5 or 6 months old. If she wasn't peeing at 20 minutes we put her in the crate and tried again in 5 minutes. Which might not be feasible when you are in a high rise (thinking the sheer time to go from timer goes off, get puppy leashed, walk to elevator/stairs, go downstairs, find a suitable potty space, come back home).
I had pretty much the EASIEST set up (single story home with a fenced backyard) and I was overwhelmed with EVERY SINGLE ONE OF MY PUPPIES. It's a huge transition to go from "no puppy" to "ahh puppy!" but it does get better. Every day you have a wealth of interactions to help train both of you to make your lives easier.
My partner has the same complaint. Molly will do things for me that he just can't get from her (mainly I get to be lazy and stand at the door watching them and they will come back to the door vs me having to go get them and Molly fetches for me and won't for him... BUT he gets calm Molly. She'll stand next to him and just be chill and get pets. But she wants to be laying on top of me checking a bone in my face or chewing on my arm or pulling my hair, etc) I think it boils down to what your puppy sees you as. I'm the fun one who plays with her all the time but I also don't put up with her ****. She doesn't want to come inside? Ok. I will hunt you down and leash you and we will do the walk of shame back to the house. Every single time she comes in when called... she gets rewarded. Go figure she likes coming when I call. Same with fetch. She gets the ball I throw a party cause she brought it back (vs playing chase me). Now she loves brining me things (can't stop, she even gets bottles off tables to bring them to me... she counter surfed a hot sauce packet off the kitchen counter and then brought it to me). Puppies are silly riots. You just gotta know what you want her to do and then reward what you want and discourage/redirect what you don't.
