Cesar helps legendary comedian Jerry Seinfeld get better control of his two dachshunds, and an entire dog-loving community to welcome a troubled terrier mix into the fold.

Whistleblowers alert Cesar to an aggressive French bulldog/terrier mix, Simon, who attacks other dogs and animals. Simon's owner fosters other dogs and needs Cesar's help. And when a husband finds himself under attack by his wife's Tibetan terrier, Schnoopy, Cesar must help the couple rebalance their energy in order to enjoy dog ownership and their marriage.
