Of course it wasn't a service dog, but my point is that a genuine ESA should be trained the same way. You shouldn't be allowed to just acquire any animal, claim that it's an ESA (fake credentials purchased by checking a few boxes on a website or even just a willing therapist or other medical provider), and take it everywhere with you unless you can prove that it's been trained to a high standard. A real service dog stays in its "assigned" place and doesn't react even if, for example, someone steps on its tail or paws.
