Last night's all-new 'Supernatural' episode "Trial and Error" pitted Sam and Dean Winchester against one of the more vicious Hellhounds they've ever encountered, but it's next Wednesday's "Man's Best Friend with Benefits" that really goes to the dogs. The hour will see Sam and Dean wrestling over whether or not to help a former association that has since turned to witchcraft, but judging by the latest clip from Wednesday's episode, witches may be the least of their problems. Meet Sam's confusing new friend in an all-new 'Supernatural' clip inside!

Dean Winchester has certainly given his brother Sam a hard time over the years for some of the "dogs" he's been with, but things will get downright ridiculous in next week's "Man's Best Friend with Benefits." The latest clip from the all-new episode sees Sam making a new friend when a lost pooch shows up outside his door, but Dean's return sees the creature taking on an entirely different look.

From The CW's official description:

DEAN REALLY DOESN’T LIKE WITCHES — A police officer named Kevin (guest star Christian Campbell), who turned to witchcraft after working a case with Sam (Jared Padalecki) and Dean (Jensen Ackles), is plagued by nightmares in which he murders innocent people. However, when the murders actually happen, Sam and Dean are called in by Kevin’s “familiar” (guest star Mishael Morgan) to help ---- but the brothers aren’t sure they want to save a witch.
