The idea is good and cute (the AI writing is a slog to read though). But I wince a bit at seeing a pit with something looking like a mouth guard at a glance, as if they're not scary enough already.
Pits and the like breeds are scary. My previous 130# male Akita was almost murdered by a 40# female Staffordshire Bull Terrier. All 4 legs were shredded, the neck too. He survived. I cross the street when I see one.
