Scientist Thomas Trelone creates a super-intelligent dog, named Sirius. He is the only dog to have attained a humanlike intelligence. Other dogs of the same breed Trelone created, have an intermediate intelligence (they are above the dog’s average intelligence, but they cannot master human language and complex analytic thinking as Sirius does.
A sense of existential questioning suffuses the book, as the author delves into every aspect of Sirius’s psyche. The novel deals with a lot of human issues through Sirius and his experiences, his unusual nature, his ideas and his relationships with humans, showing a very gloomy, intelligent, obscure, sad, and complex tale, whose significance and depth cannot be fully understood, and is often misinterpreted.
