A book about a lost dog, who missed somebody of whom he could take care. In the end his wish comes true. A strong friendship is created between the boy and the dog. The book is designated for the most little children. Therefore, the text and illustrations are simple and the font size is larger. The book is supplemented (as a bonus) by Timotea Vráblová's guide Reading with Comprehension. It contains various tasks, assignments, and games that analyse the content of the book in an attractive way. Furthermore, they focus on children's imagination and awareness (mainly through answers to very specific questions). In the book there are principal values of goodness, friendship, responsibility, but it also points out human negative attributes, such as backbiting or hypocrisy.
