If your parent spent your entire childhood spewing ridiculous tales about the evil nature of dogs, you'd probably end up afraid of them. Cruella's son Carlos has indeed absorbed his mother's many batty, dog-hating ramblings, and, having never actually met a dog before, he's inclined to believe her. Yet when he meets the Auradon Prep pup, Dude, he's given some "alone time" with the animal with zero monitoring.
Sure, the whole point of Ben's mandate to let some villain kids enter Auradon is to give them a second chance. But this is still a pretty bad idea on multiple levels. These kids have had their sense of self (and sense of the world) warped by the most notorious villains around — it's not exactly a swell idea to immediately put them in a position to follow in their parents' footsteps. Carlos certainly deserves the chance to prove himself, but maybe not right away, or at the potential expense of an innocent dog. There's giving someone a second chance, and then there's straight-up negligence.
