Need reassurance this will get better!

We have a 4.5 month older shelter puppy, who we have had since she was two months old. Lots of stuff has gotten better (she sleeps through the night in her crate well; potty training has been great – until this week, see below; good on walks and with other people and dogs).

But I am so ready for the nipping, demand barking, jumping to start to get better. The biting seemed for a week or two like it was getting better but now she’s back at it. And this week has brought the delights of a potty training regression, which has not been as issue for like 2 months. And the demand/attention barking and jumping is so annoying.

I feel like we have been consistent with training, socialization, we both work from home so she gets taken outside a ton. We don’t repeat directions, she only gets treats with “four on the floor”, we reward calm behavior, lots of lick mats, kongs, chew toys, sniff mats, etc. Although she does great in the crate overnight, she never really took to it during the day so she doesn’t have enforced naps. But otherwise, I feel like we have been so consistent with recommended training and tips.

I guess we just have to keep tolerating the annoying puppy behavior?? And keep at the training?? And it will get better when she’s, what, 6 or 7 months old??? Just need some encouragement because it’s really wearing on all of us.
