As narrated by Tuesday, Tuesday Tucks Me In is a day in the life of this service dog extraordinaire and tail-wagging ambassador for all things positive and uplifting in the world. The book takes us through a typical day of adventures, starting with Tuesday waking military veteran Luis Carlos Montalván in the morning and greeting him with dog breath in the face, and then ending with Tuesday cuddling up to Luis on their bed, the last moment they spend together before sleep.
