Jeanette
From Q to H
I have recently learned that there are service animals (who have rights to go places and live places even if pets are restricted) and emotional support animals (who only have rights to live places). Service animals *should* have a lot more training and have identifiable tasks they perform for their person (Callie for Amanda is a good example, as are things like Dogs for Diabetics and Guide Dogs for the Blind). Emotional support animals don't have identifiable medical tasks, but do what it sounds like they should - like Jeanette's cat. And is probably what the dog in the initial post is.
But sometimes people can't cope (emotionally/psychologically) with being outside where other people are, so they bring their service animal with them. I'm okay with outside and people. But other people aren't so lucky.
