Следы на асфальте

Once the boy Vova went off to ride a bicycle and disappeared for the whole day. His puppy was waiting for his master at the door, but he did not come. An adult dog, Barbos, passed by, who decided to ask the puppy why he was so sad. Since there was still nothing to do, he decided to help his little friend to find the boy. Soon they came on his trail and, thanks to their scent, were able to recreate all the events that occurred this day.
