"Young red-haired dog — cross between a Dachshund with a pooch — a very similar face on Fox" named Kashtanka has lost his master, carpenter, Luca Alexandria. She tries to trace him but to no avail. Late in the evening, exhausted, falls asleep in their boots at the door of the porch, where she accidentally finds nekit Sukhanov - the mysterious stranger later turned clown. He caressed the animal and holds him in the circus. Kashtanka gets a new nickname Aunt. The dog is in unfamiliar surroundings and meets up with other animals — a goose, Ivan Ivanovitch, cat Fyodor Timofeyevich and a pig Sow Ivanovna. Mr. Georges teaches Kashtanka various tricks and trying to come up with a new number. However, Gus died tragically (judging from the descriptions, it was accidentally killed by a horse stepping on it) and the debut of Kashtanka is not over, as it is during the presentation recognizes its former owners — Luca Alexandria and his son Fyodor and with joyful barking and rushes to him. "Aunt" takes on former owners.
