Oskar de Vries is a dog spiritualist.
Oskar de Vries is dog spiritualist. He's quite arrogant and refers to the Dog Whisperer as a talentless showoff. He is eccentric and somewhat delusional. The techniques that he uses are bizarre as is his behaviour. When Hank learns that Lady Bird is deaf, Oskar suddenly takes credit for this realization, even though he had absolutely nothing to do with resolving the issue.
In the episode Doggone Crazy, Lady Bird inadvertently bites Hank's hand when she becomes frightened due to thunderstorms and is put on the vicious dogs list. As a last resort, Dr. Yandell, the Hills veterinarian, suggests that Hank take her to a dog spiritualist which he reluctantly agrees to.
