How can I properly execute the 3 legged dog pose in my yoga practice?

To properly execute the 3 legged dog pose in yoga, start in a downward facing dog position. Lift one leg up towards the ceiling while keeping your hips square. Engage your core and lengthen your spine. Hold the pose for a few breaths before switching to the other leg. Remember to breathe deeply and listen to your body's limits to avoid injury.
