In dogs, prey drive manifests as chasing squirrels, birds, cats, or even joggers and cyclists. Breeds developed for hunting (terriers, sighthounds, herding breeds) typically have stronger prey drives. Cats display prey drive through stalking, pouncing, and the characteristic butt-wiggle before leaping. High prey drive is not aggression in the traditional sense but can be dangerous if directed at small pets or children. Management includes secure fencing, reliable recall training, leashes in unsecured areas, and appropriate outlets like flirt poles, lure coursing, or interactive toys. Suppressing prey drive entirely is extremely difficult because it is hardwired, but redirecting it into structured activities satisfies the instinct safely.
