For ten points, name this sun god from Slavic mythology.
In the pre-Christian pantheon of Kievan Rus, this god shared his role with Khors, a similar deity possibily borrowed from Persia. In the Old Russian epic poem "The Tale of Igor's Campaign", the Russians are called the grandchildren of this god. This god's father slew the serpent Zmey, while this god's brother was a thunder god related to the Baltic god Perkunas. This son of the fire god Svarog was allegedly married to a happiness goddess for whom a shitty brand of Soviet car was named, Lada, and this god had a dog's head and traveled in the sky in a chariot.
