Are you located near this ?
This is a petsmart location. If I were you I would just join a puppy class and forget about worrying what happened in the past and just move forward. If they ask a ton of questions just say you want to get some socialization because that is what you ave indicated here. I wouldnt offer up what type of dog you have unless they ask and then this way you are going into a class without any thoughts from previous things that have happened and they have no bias with the dog.

"UNTIL ONE HAS LOVED AN ANIMAL, PART OF THEIR SOUL REMAINS UNAWAKENED"
He is your friend, your partner, your defender, your dog. You are his life, his love, his leader. He will be yours, faithful and true, to the last beat of his heart. You owe it to him to be worthy of such devotion.
