Stopping
The dog interrupts the movement of another dog, using behaviours of varying intensity, ranging from glances, cutting across the other dog's path, or a lateral or frontal stance, to physical contact and knocking down.
(Capra, 2011)

In this interaction between two females, the Staffordshire Bull Terrier follows and then cuts across the path of the young German Shepherd, who reacts with a crouched stance and lowered head, tail between her legs and and rounded, hunched back. The German Shepherd licks her nose and moves away; the Staffordshire follows her, crowding and stopping her, then assuming T2 position. The German Shepherd licks the Staffordshire's muzzle, and moves away. The Staffordshire again follows her and the German Shepherd lowers her hind legs and head, ears flattened, then finally stops and sits, averting her gaze to avoid eye contact and licking her nose.
