In the season 12 finale of the 3rd season series, Oakley the dachshund takes a trip to his local dentist office. This is a dental office full of dogs! Oakley first walks into the waiting room, where he greets a border collie receptionist. Then he takes a seat next to a poodle and fluffball. Then another white fluffball dog who works as a hygienist walks in to call Oakley's name. Oakley follows the dog to the dental room, where Oakley, with his cute short dachshund legs, jumps up onto the chair. Crusoe is playing Dr. D, the dog dentist, who gives Oakley his treatment.
