Sick as a Dog is the 40th episode of the fan fiction series, The Adventures of Amy and Tiff. It was released on the day before Leap Day (February 28, 2012).
Buto "mistakenly" feeds his dog Butcher foods that dogs should not eat (like fried bacon, cheese crackers, and cheeseburgers), causing him to get sick. To make matters worse, Cappytown does not have a single vet in duty (Dr. Yabui is not a vet because he never operated any pets in his life). Therefore, Butcher is to be treated at the Station Square Pet Hospital. Buto learns in the end that not only he shouldn't feed pets food he eats, he must also believe in other people's opinions about pet nutrition.
