Kevin Hart's wife, Eniko, took her Dobie to the animal hospital Sunday night in L.A., in the wake of the sexually explicit video showing her husband in a provocative situation.

Eniko hasn't been seen since Kevin posted a video apologizing to his pregnant wife and kids for getting himself in such a "situation."

She's wearing her wedding ring ... in fact, in the photo she may be making a point of it.

TMZ broke the story, Kevin says someone has tried extorting him for 7 figures over the video, which shows Kevin cozying up to a woman. The tape also shows a naked man in a bedroom who definitely looks like him.

As we first reported, the extortion demand actually reached 8 figures at one point but the extortionist lowered it back down to 7.
