Pepe, a child with childhood diabetes, and his family visit a farm-school where puppies are trained to take care of people and carry out many important missions. This little dog, through his sense of smell, has learned to detect if there is a problem with the child’s health. When the family learns how to treat the puppy, they take him home, where they enjoy their coexistence and little adventures. But the day Pepe needs him, Toby shows what a good companion he is and how well trained he is.
