Eighteen-month-old Oso, the youngest of the Los Diggities pack, is captivated by the lights, music, and especially the delicious scents of his first Christmas with Xena, Oscar, and their zany human, Jeanie. He even has his own Christmas stocking. On their Christmas Eve walk, he discovers a chocolate wrapper and tastes it - much to Jeanie's horror. "Never eat anything you find while out on a walk, especially chocolate!" she tells him, taking the wrapper from his mouth and tossing it in the trash.

Despite Jeanie's warnings, Oso finds a box of chocolate-covered fruits and nuts underneath her Christmas tree. It smells so delicious that he can't resist breaking into it. But after devouring the last piece, he begins to feel really strange.

What happens next threatens to not only ruin the Los Diggities' first Christmas together, but could cost Oso his life. Will he survive? What can Jeanie do? And how can Xena and Oscar celebrate Christmas without their best buddy, Oso?

A humorous, heart-warming story (and lesson) for kids of all ages, A Los Diggities Christmas describes what happens when Oso ignores the warnings of those who love him, follows his nose into trouble, and ends up in a life-threatening situation. It provides insight into the kinds of foods that, while perfectly fine for most humans, can be fatal to dogs.
