You’re grossly misrepresenting what this is. She got desserts and noted him as food motivated. That’s insulting. He only got happy because there was food for him to eat, really? No discussion of why he was sad before, just get him snacks and move on? Maybe talk to him and ask why he seemed upset before desert instead of just giving him a snack and hoping it’s better.

The woman here is trying to change his mood or behavior through dog training techniques instead of figuring out why he feels or acts a certain way. Is he aware that she is literally treating him like a dog? It comes across as her caring about his behavior in the moment more than his overall mental health.
