The possible sequence

Orient, watch, eye, stalk, chase, grab, carry, shake, consume. Not every dog shows every part. Herding behaviour, predatory behaviour, frustration and play can overlap. Chasing is often self-reinforcing. High drive does not automatically mean aggression.

Common triggers

Wildlife, cats, livestock, joggers, cyclists, vehicles, running children, other dogs and thrown toys.

Safety guidance

Recall alone is not sufficient where consequences are serious. Use secure spaces, barriers and appropriately handled long lines. Muzzle training may be part of a responsible plan. Dog-to-cat suitability must be assessed individually; peaceful behaviour with a familiar household cat does not guarantee safety with unfamiliar cats. Prevent rehearsal while building alternative responses.
