Aggression towards strangers is often rooted in fear, uncertainty or a learned need to protect space. Progress begins by reducing pressure and helping the dog form safer associations with unfamiliar people.
Start with early, positive socialisation
Introduce different people, environments and everyday sounds gradually. Keep each experience calm and pair it with food, play or distance so the dog can remain below its stress threshold.
Use reward-based training
Reward relaxed behaviour, attention to the handler and successful disengagement from a trigger. Avoid punishment, which can add fear and make warning signals harder to read.
Manage known triggers
Use gates, distance, a lead and a quiet retreat area when visitors arrive. For any bite risk or persistent aggression, consult a qualified veterinary behaviour professional.
