Comments: The vestibule is not a good place to bring dogs. However, if you must, hike in from the bottom; the top passes over a number of large steps that are too steep for the canines. Beware: the whole area is full of lose shale.
Look for a crack in the back-right side of the cave to belay from for third pitch. Also, it's easier to go left about two feet and climb "over" the weirdness instead of wedging yourself in at the beginning of the third pitch.
