A dog leg is the error that happens when the second bend of an offset, saddle or back-to-back is rotated relative to the first, so the conduit twists out of plane and will not sit flat on a wall or floor. It comes from the pipe rolling in the bender between bends. Small ones can sometimes be stomped or twisted out; bad ones go in the scrap pile, and they are the first thing a foreman spots on a finished run.
That offset has a dog leg, lay it on the floor and stomp on it, or cut it off and bend a new one.
Sight down the pipe after the first bend and keep a level on it; stopping the pipe from rolling in the bender is the whole trick.
