I have the same situation going on. I am so happy to have a manager who has a toy breed and understands me. I put my dog in a crate to see if it help, and oh my goodness it was worse. I came back and I could hear him in the parking lot. No regular bark either; it sounded more like someone was killing him. And they have told me he barks nonstop until I come home.
My suggestion is to find someone to pet sit. I don't have much money so I use friends to petsit once in awhile. If your little one is trained I'm sure someone will be more than happy to look after her. Can you lock her in the restroom with a Himalayan Chew?
As far as your neighbor, record her dog barking and call the cops on her as well.
I'm not for or against debarking, but it will be my very last option. Good Luck!!
