If applicable, the crown or crowns are symmetric and typically located on the top of the ridge. Multiple crowns on the ridge are accepted if they are symmetric through the spine.

The movement of a Phu Quoc Ridgeback should be tireless, free-flowing, harmonious, and regal. At the trot, the forelegs and rear legs are moving in parallel straight lines and in line with the body, neither turning in nor turning out. When seen from the front the shoulders, upper arms, elbows, forearms and pasterns move in one straight line. When seen from behind the upper and lower thighs, stifles, hocks, and rear pasterns are also in line. The feet should not turn inward or outward. Long strides appear effortless as the proud head is held high. Overall the dog should have a well-balanced flow with smooth rhythm.
