Собачье сердце
Voronoff was the prototype for Professor Preobrazhensky in Mikhail Bulgakov's novel "Heart of a Dog", published in 1925. In the novel, Preobrazhensky implants human testicles and pituitary gland into a stray dog named Sharik. Sharik then proceeds to become more and more human as time passes, picks himself the name Polygraph Polygraphovich Sharikov, makes himself a career with the "department of the clearing of the city from cats and other vile animals", and turns the life in the professor's house into a nightmare until the professor reverses the procedure.
