I would not leave my pup overnight in a facility where no one is there at night, especially after surgery. I know a lot of people do it, but it is not for me.
I hope that you can find a vet closer to you. There has to be a good vet in your area. Maybe if you ask around on YT you might find someone in the Pittsburgh area who has a vet they can recommend. You really need to have a vet close by that you can count on.
Hope that all goes well tomorrow. I agree that you and the vet need to discuss this at length. Good luck.
I will keep Rosie in my thoughts and prayers.
