An Inus' tail isn't flesh, it can flare up in anger and/or for protection, it's also used for attracting prey or a mate. They have psychic powers like making things float, reading minds etc. The mouth on the back of their heads are used to scare off enemies, and to eat while cleaning their young. They don't live in packs, they leave their young after a few months. The ring-like thing around their neck holds their powers, once the ring is broken the creature dies, if it's just a crack then it's hurt and can recover within time. The males fight over the females/mates, the winner only gets his mate if the female/male bows down (lays down). If she/he doesn't get bowed to, then they end up with no mate.

Idk why I put "She/he" if only the males fight for a mate ;-;
