Custody

I adopted a dog from a man who got her at a rescue. We have a written agreement. The rescue got wind and now wants me to return the dog to them or fill out an application. I don't agree with a couple of their policies so struggle with the app. I am happy to give references, home visit whatever to keep her. The dog is very shy and thriving in her new environment and I don't want her returned to the rescue. All communication has been with the previous owner, who is a really good person. I don't want problems for him. We both want what is best for the dog.

My wife adopted out my dog without my permission. Fill out a form online. Was told I could not back out after she filled out application. She had been told several times the dog was not to be adopted out. Do I have any chance of getting my dog back?
