Desexing for Dogs and Cats: What You Need to Know

Desexing (also known as sterilisation or neutering) is a routine surgical procedure that prevents dogs and cats from reproducing. It’s strongly recommended for all pets not intended for breeding, and offers significant health, behavioural, and community benefits.

Desexing Explained: Answers to the Most Common Questions

What is Desexing?
  • Males (Castration): Surgical removal of the testicles.

  • Females (Spay): Surgical removal of the ovaries and uterus.

The ideal age is between 4 and 6 months, but pets can be desexed at almost any age. Desexing before 6 months offers several health and behavioural advantages.

Benefits of Early Desexing

  • Prevents unwanted litters, which can be costly and contribute to pet overpopulation

  • Reduces risk of serious diseases like testicular cancer, prostate issues, pyometra, and mammary tumours

  • Eliminates female heat cycles

  • Lowers aggression and roaming, especially in males

  • Reduces council registration fee

If your pet comes into heat before surgery, let us know. Unless urgent, we may recommend waiting 2–3 weeks after the cycle ends, as the uterus is more delicate and prone to bleeding during heat.

  • Reduced sexual behaviours (e.g. marking, mounting, howling)

  • Males are less likely to fight or roam

  • Females are less likely to urinate indoors during heat

Desexed pets may have lower energy needs, so it’s important to adjust their food intake and maintain regular exercise. Obesity is preventable with proper care.

A retained testicle (cryptorchidism) occurs when one or both testicles don’t descend into the scrotum. Abdominal surgery may be required to remove them.

Desexing is recommended once:

  • Puppies or kittens are fully weaned

  • Milk has dried up

  • Mammary tissue returns to normal

Save on future anaesthesia by combining desexing with:

  • Microchipping

  • Vaccinations

  • Heartworm testing

  • Baby teeth removal

  • Dew claw removal

  • Umbilical hernia repair

  • Stenotic nares/soft palate surgery (for brachycephalic breeds like Pugs, Bulldogs, Frenchies)
