I read in the newspaper on space dogs Ugolka and Veterka: "According to some data, Veterok before flight was generally known as Bdnook due to the respective powerful abilities of the body. The Soviet space dog did not wear such a name, and the nickname was sub-edited, although everyone knew that it was such a "window"... The dog in some way predetermined the fate of the Bulgarian cosmonaut Kakalov, who was allowed into space, but for every case was renamed Ivanov.
