''Hair of the Dog'' was the sixth studio album by the Scottish rock band Nazareth, released in 1975, on A&M Records. The album was recorded at Escape Studios, in Kent, United Kingdom, and is the band's biggest selling album, having sold two million copies worldwide. After three albums with Deep Purple's Roger Glover producing, Manny Charlton stepped into that position, one he filled for several subsequent albums. It was Nazareth's first big hit album (aside from the minor success of ''Razamanaz''), including classics such as "Love Hurts" (on the US version, but not the Canadian/European, it replaced the original "Guilty"), "Hair of the Dog", "Beggar's Day" and "Please Don't Judas Me". The album title is often considered to be a shortened form of the phrase describing a folk hangover cure, "''the hair of the dog that bit you''". However, according to Dan McCafferty, the title is a play on "heir of the dog", ie. a "son of a bitch". This was the title the band had intended for the album, but the label did not approve. The title track is sometimes mistakenly called "Son of a Bitch" because of its chorus ("now you're messin' with a son of a bitch"). The remastered compact disc, first released in the mid-1990s, features bonus tracks. - Wikipedia.
