Portland State University sponsored a workshop on the “human Puppy community” — a type of sexual fetish where people identify and live their lives as dogs.

Video of the event shows an instructor telling students never to pull the tail of a human puppy because “a lot of tails are butt plugs.”

The February workshop which was held as part of the taxpayer-funded university’s annual “Sex Week,” featured two men in BDSM-style canine outfits, walking around the room on their hands and knees, growling and sniffing each other’s rear ends while their “handler” explained the ins-and-outs of their relationship.

Advertisments for the event announced it would be led by “Pup Turbo,” whom the university noted was the “NW Puppy 2016.” Pup Turbo was featured in a Vice piece titled “Young Gays Are Sniffing Out The Pup Life” which noted that he is a teacher and researcher at UC Santa Cruz.

That article described how “Pup Turbo” leads a “pack, whose hierarchy includes beta and omega pups, a barking order he keeps in place with a soft touch and familial nudge.” He identifies as “Pup Turbo” on his public Facebook page, which has more than 350 followers.

In the video, one student can be heard asking if its possible to live as a “kitty” rather than a puppy. The instructor answers yes, noting he met “a pig once,” and that there’s “a rat in Seattle.”

The Guardian recently did a feature on the human puppy community, titled “The men who live as dogs.” The article described how the human puppies chew on squeaky toys, eat out of bowls, and otherwise live as dogs.

The university did not immediately return a request for comment.
