The CW has released a sneak peek and promo from next week’s episode of Supernatural, titled “Man’s Best Friend with Benefits.”

First, the sneak peek:

In this clip, we see Sam opening the motel door when he hears a dog whining outside. The dog immediately runs into the room and makes itself comfortable on one of the beds. Sam, ever the dog lover, looks for tags (there are none) and gives the dog a belly rub.

When Dean returns to the motel, Sam stops him before he comes inside to tell him about the dog. His words become amusing double entendres when Dean looks inside the motel room to see that the dog has become a woman.

According to the synopsis, the dog-turned-woman is the familiar of a witch named Kevin, who is a cop “who turned to witchcraft after working a case with Sam and Dean.”

Kevin has been “plagued by nightmares in which he murders innocent people,” and his familiar turns to the brothers for help “when the murders actually happen.” However, “the brothers aren’t sure they want to save a witch.”

We also have a promo for the episode:

“Man’s Best Friend with Benefits” airs Wednesday, February 20 at 9 p.m. ET.
