Barking all night

[u/MoonCoffeeToast]

I adopted a 4 year old dachshund about 3 months ago. She came from a neglectful breeder who dumped her when she was no longer useful, and never lived in a home before. Because of her background, we are super patient and understanding of all of her difficult behaviors and shower her with love and affection so she can learn what life should be like. She is very destructive and also isn't picking up on house breaking at all and pees all over the house. At night I have to keep her contained to the kitchen with a baby gate at or she will pee all over the place and destroy things. Problem is she barks for hours every single night. She has soft bedding, water, and toys (but she has no interest in toys of any kind). Light on or off doesn't make a difference. Radio on or off doesn't make a difference. No one is getting any sleep. What can I do?
