Yoshi's Castle

Cesar is in Singapore working with a fearsome dog named Yoshi. After Yoshi attacked a dog in the community dog park, his owners have kept him locked in their apartment for the past year. Cesar arranges for the owners to let Yoshi out of the apartment for the first time in a year, and he promptly tries to attack. Cesar realizes Yoshi has never had a pack leader to teach him how to behave.
