As of 1 July 2018, it is in most instances compulsory to desex a dog or cat [Dog and Cat Management Act 1995 (SA) s 42E].

A dog or cat must be desexed:

whichever is later [ss 42E and 70(2); Dog and Cat Management Regulations 2017 (SA) regs 12 and 18(2)].

Dogs and cats that were aged 6 months or older before 1 July 2018 are exempt from the requirement to be desexed. Those born on or after 1 July 2018 must comply with these requirements.

Working livestock dogs are exempt from the requirement to be desexed [Dog and Cat Management Act 1995 (SA) s 42D].

What is the penalty for failing to desex a dog or cat?

The maximum penalty for failing to desex a dog or cat is [s 42E]:

What if a dog or cat continues to not be desexed after a fine has been paid?

A further offence is committed for every 3 months that the dog or cat fails to be desexed. The 3 month period commences from the day on which the person was found guilty of the original offence, or the day on which they paid the original fine [s 42F].

What if desexing would pose an undue risk to the health of a dog or cat or adversely affect their growth, development or wellbeing?

A registered veterinary surgeon may grant an exemption from the requirements to desex a particular dog or cat for these reasons [see Dog and Cat Management Regulations 2017 (SA) reg 13(2)]. An exemption due to the health of the dog or cat may be for a limited or an indefinite period, but an exemption due to the growth, development or wellbeing may only be for a maximum of 18 months [reg 13(4)(b)]. The exemption must be by notice in writing as required by the Dog and Cat Management Board [reg 13(5)]. The Board or the registered veterinary surgeon may vary or revoke an exemption if it is no longer necessary [reg 13(7)].

What if a dog or cat was desexed interstate?

If a dog or cat has been desexed in another State or Territory in accordance with the law of that State or Territory, then it will be taken to have been desexed in accordance with the requirements in South Australia [regs 12(7) and 18(3)].
