If a dog that has been sent there to have surgery an after words put up for adoption but does not get adopted for a long time can the owner readop.

There is none

Do you have a dog already treated there?

Did the owner not pay vet bills? Most likely they will not adopt out to the original owner if they can't afford vet care for their animal.

I would imagine you can provided you meet their criteria
