''Dog & Butterfly'' is the fourth studio album by the American rock band Heart. It was released on October 7, 1978 through Portrait Records. Heart rebounded from below average sales from Magazine, as ''Dog & Butterfly'' was certified double platinum, spent 36 weeks on the charts, and peaked at number seventeen on the U.S. Billboard 200. The album contained two hit singles; "Straight On", and "Dog & Butterfly".

As Heart themselves noted on the album's release, Side 1 was the "Dog" side, and was the more "rocking" compared to the "Butterfly" Side 2, which was all ballads, with the exception of "Mistral Wind," which, in many ways, epitomized the trademark sound for which Heart would be remembered: folksy ballads shifting into searing hard rock explosions.

Though the first song on the album "Cook with Fire" sounds like a live recording it was actually recorded in the studio. Audience sounds were overdubbed on the studio recording from a live performance. - Wikipedia
