Extreme difficulty training puppy.

Age: 4-5mo

Breed: Unknown

We adopted her at 6wks.

She knows her name, comes when called, and sits on command, but even months later, she panics every time she’s put in the crate, she poops in the crate, pees in it, she’ll bark for hours straight if left in the cage, she pees and poops inside, and she chews on everything / digs holes if left alone. She bites and replacing the bad thing with a good object like a toy isn’t working. She’ll drop the toy and try to bite your hand or some other “bad” object, even with several different options for toys.

I’ve been giving her positive reinforcement whenever she uses the restroom outside, immediately marking the behavior and rewarding, it doesn’t seem to be making the difference. She has an older dog in the home (GSD) that of course is already sufficiently house-broken but she isn’t emulating that behavior at all; I’m used to training GSD’s who pick up better on what another dog is and isn’t doing.

I’m tired. We can’t go anywhere without her using the restroom in the crate. We can’t leave her out because she’ll pee or poop wherever she likes, we can’t leave her outside because she’ll dig holes and eat rocks and destroy things.

She can’t be left unattended at all, even for short periods of time, we constantly have to helicopter around her and stop her from doing the next “bad” thing.

Feeling very, very defeated and need advice.
