The Flying Dog is basically the Hot Shot without legs. Without walkers, the Flying Dog remains hovering during its operation. It also has an improved defense, as it takes five strikes to destroy. Once four strikes have been dealt, the Flying Dog simply stops using missiles and machine guns, and instead launches its plasma cannon repeatedly. It first appeared in Sonic Adventure 2.

Boss guide

The Big Foot begins by flying up and strafing the ground with machine gun fire. It’s easily seen and does not move very fast, and the player can run in a wide circle to avoid it. After a few passes with the machine guns, the Big Foot will land and the missile bays will open. Predictably, missiles shoot out at the player, who must once again run around the edge of the circle until the barrage stops. As soon as the missile pod's doors close, the player must leap high into the air and Homing Attack the Big Foot’s cockpit. After four hits, the Big Foot will collapse.

As an easier way to defeat the Big Foot in less than a minute, the player can jump on top of Wooden Containers before it destroys them, and launch a Homing Attack at it. It is also possible to hit Big Foot's cockpit with a Bounce Attack while it is in the air, although Sonic requires the Bounce Bracelet found later in the game to do so.
