What I would do about the dog ~
Call the pound and ask to speak to the director, tell the director the the story of how the dog was placed there and go into small detail of difficult child and the issues you are facing.
Next do a search for rescue groups in your area. There are breed specific groups and groups for all mixes. These groups have foster homes that will take her and match her with a loving forever home.
I would help the dog, but I would in no way let difficult child know that I did.
The director of the pound should also be able to refer you to some groups, most pounds work with alot of them.
What kind of dog is she? If she is full blooded, then each breed has a group that works to keep their breed out of shelters.
I am sorry that difficult child was so ugly to you. I know how you feel. I would take this time and help yourself. Do what ever it is that brings you some happiness.
She will contact you again. You do what you have to now to be strong when she does.
