Pokémon are made by committee, have been since Tajiri's day "draw thing, submit to council, receive feedback, make adjustments, repeat until accepted/outright rejected". They also stick close to their original concept base and Game Freak based it off a hyena. Which means it's not going to suddenly become a werewolf, that's why they went and MADE a werewolf 'mon, complete with only acquiring the form at night.
