I don't get it either, but it kinda creeped me out? Probably cuz it's giving bestiality vibe, and that's just not my cup of tea. Nope. Not even in fiction world.
What in the world... this is just sad
I love my dog, shes pretty cute and often sleep on my bed... but shes my dog, just that. To seclude from real people in a delusion, or even think the poor boy should had his arm ripped off for it is just awful.
