On November 13 at 9pm EST/PST, Cesar is called to help two German shepherds, Angel and Bear, who after getting along fine at home have become aggressive at doggie daycare. Bear was submissive to Angel for over a year until he decided he wasn't going to take it anymore. Will Cesar be able to break-up this daycare dominance dilemma?

Mission Control

German Shepherd Angel came to owners Joe and Sandra Carrick in December 2004, and Bear, another German Shepherd, arrived in April 2005. They were affectionate with each other and there was no sign of any discord between them. However, when the Carricks first took the dogs to daycare, they noticed that Angel would try to dominate Bear, and he would submit almost immediately.
