The state-level rules every owner and walker in South Australia should know. Local leash lengths, licensing and off-leash rules are set by each city — find those on the city pages below.
South Australia's dog law runs on the Dog and Cat Management Act 1995. The owner and any person responsible for the control of a dog carry liability for an attack, so a walker holding the lead is directly exposed. Prescribed breeds (American Pit Bull Terrier, Fila Brasileiro, Japanese Tosa, Dogo Argentino and Presa Canario) must be muzzled and kept under effective control on a lead under 2 metres whenever in public.
Under the Dog and Cat Management Act 1995 (SA) it is an offence for a dog to attack, harass or chase a person or an animal, and liability reaches the owner and any person responsible for the control of the dog — on a walk that is the walker. From 17 November 2025 some of the nation's toughest penalties apply: a maximum fine of up to $25,000 where a dog attacks and seriously injures or kills a person or animal, rising to up to $50,000 where the attacking dog is subject to a dangerous dog order. This criminal exposure sits on top of any civil claim, so a walker needs their own liability insurance covering dogs in their care.

The Act sets out prescribed breeds: the American Pit Bull Terrier, Fila Brasileiro, Japanese Tosa, Dogo Argentino and Presa Canario (Perro de Presa Canario). When not confined to the owner's premises, a prescribed-breed dog (and a dog subject to a dangerous dog order) must be muzzled so it cannot bite and be under effective control by physical restraint — a chain, cord or leash less than 2 metres long. Higher penalties apply to offences involving a prescribed breed. For a walker this is a hard hook: if a client dog is a prescribed breed or under a dangerous dog order, confirm its status and handle it strictly to the muzzle-and-lead conditions, or decline.
SA mandates microchipping (by 12 weeks of age or at point of sale) and, for dogs born after 1 July 2018, desexing (by 6 months of age or 28 days after purchase, with limited exemptions for working and registered-breeder dogs). Every dog 3 months and over must be registered, and registration, microchip and desexing records run through the statewide Dogs and Cats Online (DACO) register, which replaced the old council registers. A 'standard' dog (microchipped and desexed) attracts a discounted registration fee while a 'non-standard' dog pays more, and councils set their own amounts. Failing to register is expiable.

Councils set the leash and off-leash map under the Act and their by-laws. The default is a dog under effective control — on a lead no longer than 2 metres — with designated off-leash areas and fenced dog parks where a dog may run under effective control, and on-leash and dog-prohibited zones (near playgrounds, organised sport, some reserves). Owners must pick up, and rangers issue expiation notices. Rules vary by council, so a walker must check each council's by-law and off-leash list for their routes.
