A gate in Fal Dara's keep. It is situated at the back of the keep and is just high and wide enough for one man on foot (TGH, Ch. 3).
Rand tries to leave Fal Dara when the Amyrlin arrives but finds all gates, including this one, guarded (TGH, Ch. 3).
When Trollocs and Fades attack the keep, they enter through the Dog Gate. The guards were killed by someone on the inside. They also leave this way, taking with them the Horn of Valere (TGH, Ch. 6).
