If you give your dog away and you want her back.......?

Look, you gave up the dog, and I understand that was hard, but you can't just go and rip the dog back from its new owner- that's not right or fair. If you did get the dog back, the same 'other reasons' would come back and cause problems again; you also risk being thrown out of your apartment if you already have one dog. You made a good, grown up decision, and the dog will be better off for it.
