I don't want the dog what i can do

If you want to surrender an animal to the shelter, you need to take it there so they can process it and you'll have to pay a fine

The dog probably does not want you either - they can feel your emotions. Put it up for adoption on line or bring to the shelter

It's 20 dollars usually.

Not a fine but a fee

You will want to call and schedule an appointment to surrender the animal. You can't just take them in.
