Desexing your dog, Kaipara District Council

Desexing your dog

​When you can get your dog de-sexed

  • Dogs can be de-sexed from six months of age.
  • If a female dog (bitch) is in season, de-sexing can be done four weeks after. To learn more about this, speak to your vet.

What you need to do

Book a de-sexing appointment with a vet. You can find a vet through the Yellow Pages.
Only a veterinarian is allowed to perform a de-sexing operation. To know more about surgical procedure offences and provisions, see the Animal Welfare Act 1999.

Cost of de-sexing

The cost varies among vets.

What happens during and after de-sexing procedure

  • The vet will remove your dog's reproductive organs while it is under an anaesthetic.
  • You will be able to take your dog home the same day, unless the vet advises you otherwise.

Financial assistance

During June 2020 we're offering a special offer of $50 de-sexing and micro-chipping for Community Services cardholders (residents must live within Dargaville and surrounds). For more information email or text 027 2029777.

This offer is valid until spots run out. It's supported by the Lotteries Commission, North Auckland Dog Rescue, Dargaville Veterinary Centre and NexGard.

Benefits of de-sexing your dog

De-sexing does not change the personality of your dog. It makes them more sociable and easier to train and handle.

Health benefits

  • De-sexed dogs generally live longer, healthier lives and have a lower risk of getting various cancers and diseases of the reproductive organs.
  • Male dogs have no risk of testicular cancer.
  • De-sexing prevents the male dog's prostate gland from enlarging, removing their discomfort when urinating and defecating.
  • Female dogs (bitches) have a lower risk of getting mammary cancer, cystic ovaries, prostatic disease, perianal tumors, perianal hamias and acute uterine infections.
  • Bitches have no risk of pyometra, a life-threatening womb infection.
  • Bitches have a lower risk of false pregnancies (showing pregnancy symptoms without carrying puppies)

If you have a good reason not to de-sex your female dog, keep her securely confined when in season.

Behavioural benefits

  • Dogs are less likely to wander, roam or stray and are therefore less likely to be hurt in road accidents.
  • Dogs are less likely to be aggressive and are easier to train.
  • De-sexing will prevent male dogs from searching for bitches in season and fighting with other dogs.
  • Male dogs are less likely to behave anti-socially, e.g. mount people's legs and mark their territory.

De-sexing helps control overpopulation of dogs

De-sexing eliminates reproductive drive in dogs. This reduces the number of unwanted puppies.

Strays and surrendered animals can overpopulate animal shelters.
