If a dog attacks someone, then its owner may be responsible for any damage caused by the dog. However, the way in which you may be liable will depend on the circumstances. Under the Dog Owner’s Liability Act, you are liable for any damages caused by the dog if you are the dog’s “owner” as defined under the Act. However, even if you are not the dog’s “owner”, you may still be liable under the Occupier’s Liability Act for failing to ensure that your premises were reasonably safe for people coming onto your property. You may also still be liable at common law for negligence.
