It sounds like legally the dog now belongs to you and Mike. Take that man's butt to court. Even if he lies, he has absolutely no proof. And you have a lot. Any judge would be stupid not to rule in favor of you because of that 30 day law.

Maybe once the guy sees he's neutered he won't want him anymore. Wishful thinking I know, but I've seen it happen before.

I will be praying for you and awaiting Tobey's return to his real home, which I know will happen.
