When a dog barks, growls or lunges at strangers, the behaviour can be distressing for everyone. It is important to remember that aggression is often a response to fear, anxiety or feeling trapped rather than simple disobedience.
Common causes
- Guarding instinct: some dogs are naturally more alert around their home or family.
- Past experiences: frightening or painful encounters can shape defensive responses.
- Limited socialisation: unfamiliar people and situations may feel threatening without gradual positive exposure.
Observe the dog’s body language and identify the distance at which it can still remain calm. Do not force greetings. A veterinarian should first rule out pain or medical issues, and a qualified behaviour professional can create a safe training plan.
