Children love pets and it is positive that they are not afraid of them, that they show them affection and play with them. But also they have to make themselves responsible for their mascots, to look after them and take care of them properly. That, precisely, is what Teo will do in this chapter. Teo, together with his father, takes Puc to go for a walk. Teo learns that Puc can’t go untied along the street pouncing on people or scratch the grass with its legs. He can’t leave the street dirty when Puc uses it as its particular bathroom.
