Possibly. Skyrim is supposed to have the largest population of lycanthropes in Tamriel, so it would make sense. If vanilla Skyrim's population of lycanthropes is supposed to be large, and there's literally just about no lycanthropes in the entire region, then what's supposed to be a medium or small population of lycnthropes in a province, two? It also has been a common complaint that there are no wild werewolves and
Spoiler no way to become a werewolf outside the Companions, so it could be a possibility.
For now, we just know that you can be a werewolf again if you were a werewolf before being a vampire lord.
