I don't think that is a one answer fits all quesiton, personally. Every situation is different. I would be much more willing to pay a rehoming fee to a responsible person who has already had the dog fixed and for what ever reason it was just a bad match. When you have one that wasn't fixed beforehand, and don't really know what the dog was used for prior to being rehomed, or why it was never fixed to begin with....hypothetically, it is just putting money back into the pocket for them to do that to another dog. But, depending on the situation, if you screen the person well it may be worth paying. I should add, screening goes both ways...
