The latest episode of "Haunted Highway" (Tue., 10 p.m. ET on Syfy) found Jack Osbourne and Dana Workman in Nevada.
The pair was hoping to pick up the scent of those monsters most feared by "Supernatural's" Sam and Dean Winchester: hellhounds.
The hounds are supposedly the spirits of vicious dogs that were once abused by miners in the area.
As Workman walked through the undergrowth, they both heard a growl. Then, through his thermal camera, Osbourne spotted some kind of four-legged creature moving toward her.
"Oh my God, Dana! Go! Run, run, run, run!" he yelled.
Although they agreed it wasn't proof of hellhounds, the pair didn't find any other animal in their vicinity.
The spine-tingling quest continues on "Haunted Highway," Tuesdays at 10 p.m. ET on Syfy.
