De-sexing FAQs

Most dogs do not have to be de-sexed (this is also called sterilised, fixed, spayed, neutered or castrated).

What are the benefits of having my dog de-sexed?

  • your council may offer a discount on your dog's registration fees
  • no unwanted puppies

  • less pressure on dog homes and the need to put unwanted dogs down
  • less behavioural problems in dogs such as roaming, aggression and territorial scent marking by male dogs
  • less mating behaviour and false pregnancies in female dogs
  • female dogs won’t go on heat and therefore will not have to be confined while on heat
  • fewer diseases and illnesses such as some cancers and infections in female dogs and cancer and prostate problems in male dogs
  • de-sexed dogs usually live longer and have healthier lives

When should I have my dog de-sexed?

Most dogs are de-sexed between 3 and 6 months of age but it should be done before your dog is 5 or 6 months old.

RSPCA Australia recommends early age de-sexing from the age of 8 weeks because it is simpler and recovery is faster.

Where can I have my dog de-sexed?

De-sexing is an operation safely carried out by a trained vet who has the right equipment.

It is against the law for a person to carry out this operation if they are not a registered vet.

Can the council make me have my dog de-sexed?

Yes, dangerous or restricted breed dogs must be de-sexed and microchipped at the cost of the owner.

A dangerous or restricted breed dog that is not de-sexed and microchipped may be seized and held in a pound by a council.
