This glitch works best on Solo, but you can do this online with friends also...

For this glitch you have to have already turned on the power before the dogs.

On the left and right of the turret next to the teleporter, there should be two sets of stairs, go up to one it doesn't matter which.

Sitting on it and the stage should be a few boards diagonal like a slash (/). Get onto them (during dogs) and the dogs should just stand there and watch you. If you're getting attacked adjust where you're standing...
