Cowboy Bebop Wiki

Doggy Dog II is an arrangement of Doggy Dog using an eclectic mash-up of several diverse musical styles including jazz, ska and drum-and-bass. It received an official release on Disc 2 of the Cowboy Bebop Boxed Set.

The song featured as VT fought the Memphis brothers in Mac's Diner (causing Spike to spill his egg). While Doggy Dog played, after an inserted shot of the Red Tail in flight, the sequence cuts to the bounty hunters opening their flick knives, and soundtrack seamlessly cuts from Doggy Dog to Doggy Dog II.

Doggy Dog III can be heard later in the episode.[1]
