I would take her back and let her play so she will not be scared but I would watch for that dog, and if you see him off leash I would grab Gracie up and go find that man and tell him his dog has gotten off its leash again...and when he says something like he let him off, I would politely tell him that all dogs are suppose to be leashed.....I would also say politely that you are surprized he would let him off leash since he attaches puppies.. and I would tell him in front of everyone.....
