I know how it is with not having everyone on board to train the dog… thankfully ours has realized that while she can do stuff with one person, she can’t with me or my mom (and its just silly things like wrestling or pulling socks off his feet). It can be very very frustrating, but she has the “house rules” down for the most part now. (teaching her “wait” was the hardest one)
I second the crate with the frozen peanut butter kong.
One thing I noticed when you wrote your next post, she seems to LOVE structure. I bet with the moving and everyone (and things) not where they should be she’s gotten worried/anxious and now has learned that when she screams, she gets something.
If you have to in the mornings make it a habit that she “goes to her room/spot” at a certain time (Yes our dog knows the command and goes to her crate with it) and then get everything out of the way and then when it is quiet again let her out. Even if you don’t have a crate, a room with a door that shuts can be used as well.
Also, don’t let her out if she screams at you. I had to do this with our puppy. She has to sit, and wait, for us to open the door of her crate, quietly. If she screams, walk out of sight. You can do this for a “room” as well. Wait until its quiet, come back in. It may take a few times but she sounds very intelligent and she should get the idea that quiet= out of crate/room mom time.
If you can follow the same rules for feeding/training/treats/clicker (screaming=no attention/reward), she’ll probably catch on pretty quickly. Be wary though if you try to teach her “quiet” she may learn that screaming and then going quiet will lead to treats as well (ask how I know that one).
eta: Our dog trainer recommended the “stop that spray” over the bark collar. We used the bark collar on our pup but she just learned how long it took for it to “reset” and would get noisy again. The spray has calming agents in it so that might help if she’s anxious as well. It’d be the same idea as the collar, but you’d have to be spot on for the “punishment” and repeat with any sort of avoidance (hiding and screaming) followed by praise for being quiet/showing her that everything is still okay after punishment and that the quiet is what you want.
Note: I am not condoning chasing her with it. That will lead to nowhere. But if you can catch a moment between where she is quiet, it may work to spray, pause, praise. I can ask my trainer about the issue if you like.
