A white puppy entered the yard of the canine university. A small flock of puppies ran after him. The puppy entered the building. The main hall was large and spacious. On the wall, the puppy saw frames with photos of puppies and newspaper clippings. Turning, he saw a worker. She pointed to the height meter. Approaching, he stretched out that there is strength. The woman allowed him to go further. The puppy was delighted.
Puppy training in class with other puppies has begun. The puppy had to lead a blind person through an obstacle course. He failed. The puppies collected food in a bowl. The main character was shorter than the others, so he had difficulties.
Another test came, which he also failed. The puppy was chased by failure, over and over, over and over again.
He looked again at the wall in the main hall. In one of the photos, he saw a puppy that was shorter than the others, like him. He decided to study harder. He will start to get it right. For the first time, he successfully passed the test.
The day of the exam has come. He flunked it by failing the judge. They kicked him out into the street. Approaching the statue of the dog behind the fence, he saw a blind woman with a cane. Going to the window of the room where the exam was being held, he saw that all the puppies had passed the exam. He began to cry. Suddenly there was a noise. Looking, he saw that woman at the construction site. He hurried to her. Running up to her, he helped her to safely get out of there. An employee of the canine university saw this. For this, he was praised and awarded a cloak. The puppy was happy and proud of him.
