Back when Siwon was active on Instagram, it seems he uploaded a post in the voice of his dog Bugsy, and wrote, "Because I bite people, I receive training once a week for an hour (with mom and noona). I don't know what it all is yet. I'm happy because the teacher gives me food. On Saturdays, this is how I live..."
After discovering this past post, some netizens are reprimanding the Choi family for their negligence which led to the recent, controversial incident, despite being well aware of Bugsy's biting habits.
