Section 13 of the Animal Welfare Act 1985 (SA) provides that a person who ill-treats an animal is guilty of an offence. Regulation 6 of the Animal Welfare Regulations 2012 (SA) states that unless a veterinary surgeon has certified in writing that the tail docking of a dog is necessary for the control of disease, a person who tail docks a dog has ill-treated the dog. Regulation 6 also provides that a veterinary surgeon may dock a dog’s tail if they are satisfied that the procedure is required for therapeutic purposes.
