How much do they charge to surrender a dog ?

It should be free plus you can always say you found him but aren't the owner unless he's moved chipped to you

Around $20.00

Currently, it is their policy not to intake any owner surrender dogs, but if they do it is $19. It is better to try with a private shelter.

Usually around $50, depending on circumstances and condition. But they are usually full. You'd be better off rehoming through social media

I don't know how much charged
