Okay, but we know that the Alpha roar affects wolves that aren't in their pack, so it's not unreasonable to suggest that the Alpha roar is an ability that affects shifters in general, or perhaps just weaker shifters than the Alpha. There's a multitude of possible reasons that worked.

Just because the Alpha roar (from a werewolf) worked on a werecoyote doesn't tell us that there are Alpha/Beta/Omega werecoyotes which is what Izunadara has been saying.
