One day on the porch of her "new home" in the hills of Los Angeles, Xena, a rescued seven-year-old brindle Great Dane, opens a conversation with her two best friends, Oso (an 18-month-old rescued Golden Retriever/Chow mix) and Oscar (a 10-year-old rescued Boxer) with the question, "Like, how did we all get here to Los Angeles?"

Xena had originally started out as a potential show dog-or at least that's what she had been told by her first owner. Born and raised in "the Valley" of Chatsworth, California, she speaks with a "valley girl" accent and carries herself as a princess. Due to mysterious circumstances, at the age of 19 months she was taken from her pampered life and left at a rescue shelter. Enter Jeanie, her wacky, eccentric new human, who sees the beauty in this poor, skinny creature and rescues her.

Oso, at the age of four months old, narrowly escaped the clutches of evil dog catchers in Cabo San Lucas. Born on the streets, he and his siblings enjoyed the freedom of living off of the good graces of humans and their garbage cans until dog catchers came and took all but Oso away. Rescued by a young couple (Saul and Rebecca, their two daughters Hannah and Marie, and their cat Sushi) - he is brought to Los Angeles where he now lives directly across the street from Xena and Oscar.

The three pals now describe their sorrowful pasts with one another and then decide to form their own pack as "Los Diggities". Joyful in their new homes and friendships, Xena the "princess from the valley", Oscar, the "wise old sage", and Oso, the young, reckless "puppy", vow to always stick together as friends forever.
