A cute puppy was born quite recently and cannot understand many obvious things. The baby still does not know what to do well and what is bad. He is trying to figure out whether to bite. To find a smart and wise teacher, the dog goes into the forest. Here he meets a beaver who is very busy, not too smart boar, cunning wolf and even a huge elephant. But the puppy could not find the answer to the important question. Frustrated, the baby returns home and sees that the cunning predator wants to swallow the chicken. What can the dog do if he does not know whether it is possible to bite or not?
