"Dog Eat Dog" is a song by Australian hard rock band AC/DC. It is the second track of their album Let There Be Rock, released in 1977, and was written by Angus Young, Malcolm Young, and Bon Scott.

It was released as a single in Australia, and included the non-album track "Carry Me Home" on the B-side, which was later released on Backtracks.

AC/DC played "Dog Eat Dog" on their Black Ice World Tour until early 2010 when they dropped it from the set list and added "High Voltage".
