The CW has released a batch of promotional stills from Supernatural season 9, episode 5, titled “Dog Dean Afternoon.”

After taking on The Wizard of Oz, Supernatural will tackle another series of children’s books: Doctor Dolittle. For the uninitiated, the Doctor Dolittle stories feature a doctor who prefers animal patients to humans since he can speak the animals’ languages.

This handful of stills doesn’t tell us much about the episode, other than that the Winchesters will be spending some quality time with canine companions.

The official synopsis for Supernatural season 9, episode 5 gives us a few more hints:

DOGGIE DEANLITTLE — While investigating two bizarre murders, Sam (Jared Padalecki) and Dean (Jensen Ackles) realize there is an eyewitness to both gruesome deaths – a German Sheppard. Anxious to find out if they are dealing with a witch, a skinwalker or other supernatural monster, the guys look up a spell that could let Dean “communicate” with the dog. Unfortunately, the spell comes with side effects that no one saw coming. Tim Andrew directed the episode written by Eric Charmelo & Nicole Snyder.

We also have a promo for the episode at the end of our recap of “Slumber Party,” which shows what are likely some of those unintended consequences.

Supernatural season 9, episode 5 “Dog Dean Afternoon” airs Tuesday, November 5 at 9:00 p.m. ET on The CW.
