Technically he's a wolf not a dog, but I couldn't help myself for this even, kouji's first couple of transformations have been unstable in which he'll attack just about anything that bothers him. Alraedy having 2 bites under his belt and a couple of intense mauling under his belt.....i love werewolves alright.

Anyways he's gonna calm down, maybe after he's been put in his place. He might actually get control himself, soon enough. Thoughwaking up nude in the morning is a normally bothersome processes.

His transformations tends to start from fear or just plain instinct, he can resist but cant delay the inevitable.
