Whistle-blower Arturo is fed up with his neighbors Jim and Sam's powerful American bulldog/boxer mix, Matilda, attacking dogs in the neighborhood. He invites them to his Dog Psychology Center to further rehabilitate Matilda and train Jim and Sam to be better pack leaders. Cesar's next call comes from whistle-blower Rose, who is extremely concerned for her friends Diana and Joe's dog, Tosha, who attacked Rose so severely that the bites left her arm scarred.
