If you fill out adoption paper do u have to take the dog when u get there

No. If you didn't find a compatible dog you don't have to take a dog. You can come back another day or not at all. Happy searching

I don't know any rescue that makes you take the dog when you get there. I have gone to two dog rescues and filled out applications but they were not a good match for me. Your match is out there somewhere might not be the one with the application. Go there and find your match.
