It didn't happen very often that Dorian was seriously afraid of getting caught. The first time it happened was at Hogwarts. He always managed to get away with it when he had fun slaughtering Hagrid's poultry, because the old half-giant had become senile and often forgot to keep an eye on his coop. Since it wasn't possible to resort to magical security measures, unless he wanted to cause chaos among the students and professors who for any other reason approached the hut, one day Professor Kettleburn had convinced him to adopt a guard dog. For Dorian, that Newfoundland puppy became an obsession.
