Is a Toy Reinforcement a Good Idea?

Ana asks: Is it possible that by preventing her from public greetings, I've sensitized her and associated novel stimuli with frustration. Could a toy reinforcement work as well as food in these situations if a dog shows significant preference for toys over food? And would a toy tend to be too overstimulating? So no, I probably wouldn't go the toy route. Ana should absolutely hook up with this local trainer that you like because this is a lot. Definitely need some serious intervention.
