This is a good glitch to piss an oppenent off in a sort of taunting way. Walking the Dog is just one of the many extensions to the Remote Chainsaw Glitch. Pretty much what happens is when you run into an oppenent with the Remote Chainsaw Glitch you are able to pull the enemy you glitched with you, and it looks funny as hell at the same time.
If you know the Remote Chainsaw this glitch is very simple, here's a quick tutorial...
2) When approaching whom ever you wich to glitch (an opponent) hold LB
3) When you reach the enemy and start the chainsaw animation let go of LB, now you can roll back, and as you do the enmy going through the animation will folllow you.
*Note: You can do this glitch whether the opponent is downed or still up.
Here is a video by GlitchingBastard representing many variations of this glitch.
