Who is liable for a dog bite?

Macau follows a strict-liability rule for animal-caused damage: (1) under Article 4 of the Animal Protection Law, the keeper is liable for damage caused by their animal regardless of fault; (2) liability may be reduced if the victim contributed through their own intentional or negligent conduct; (3) if the keeper knowingly failed to restrain a dangerous animal (no leash, no muzzle), they may also face administrative penalties under the Animal Protection Law (fines, animal seizure). Victims should preserve medical receipts, diagnosis certificates, and scene photos, then pursue civil proceedings for medical costs, lost wages, and pain and suffering.
