Thank you. Well, in this concrete case I was not worried about after aww-moment as I was more concerned how my daughter is going to react which concern forced me to prepare in advance plan "B", meaning an alternative good home for the puppy.
In other words, I believed I would be able to handle with after aww-moment, but if she would still be afraid or even worse getting the panic attacks again, I wouldn't have some other option than giving the puppy away. That's why we had to ensure in advance the alternative home for it in the first place.
