The centre of gravity is the point where the maximum weight of the body is exerted. It varies in position static animal and during locomotion.
Normally in a slow moving gait, there will be regular shifting of centre of gravity from left to the right of the midline resulted in forward movement. This will be accompanied by rhythmic sideward movement of the trunk, head and tail. These rhythmic movements of head and tail contribute much to the maintenance of equilibrium during locomotion.
