Setting the Flank means to throw out to your right or left.
It’s really simple, just face any direction, send the dog Around, and then turn and throw the disc out to the side. It is important to face forward first, as the Flank is out at 9 or 3 o’clock, and you want to condition the dog to be OK with moving out to the side after an Around.
Setting the Flank allows the game of disc to be played out to the handler’s left and right as well as out and back.
Setting the Flank opens up the whole field and is the foundation of disc dog flatwork.
