Every Dog Has It's Day is a third studio album by Australian thrash metal band Mortal Sin. It was released in 1991 through Virgin Records. The line up was recruited by Andy Eftichiou after the band broke up in 1990. As a result he was promptly sued by his former band mates. Released with the title of Rebellious Youth in Australia with another cover, released as Every Dog Has It's Day outside of Australia. For some reason the album's title is grammatically incorrect.
