If you’ve just welcomed a new puppy or kitten into your home, chances are someone has already asked, “Have you thought about desexing?” It’s one of the most common conversations that happens at a vet clinic, and for good reason. Desexing your pet is one of the most important decisions you’ll make as a pet owner, and it’s worth understanding what it involves before you book that appointment.
This guide is for Keysborough families who want the full picture: the benefits, the timing, what to expect, and why your local council actually rewards you for doing it.
What Is Desexing, and What Does the Desexing Procedure Involve?
Desexing is a routine surgical procedure that prevents your pet from being able to reproduce. It involves the removal of the reproductive organs, and the terminology differs depending on sex:
- Spaying (‘spaying’): for female dogs and cats. The ovary (or ovaries) and usually the uterus are removed. This is technically called an ovariohysterectomy or ovariectomy.
- Castration (‘castration’): for male dogs and cats. The testicles are removed in a procedure that’s generally quicker and lower-risk than spaying.
Both procedures are performed under general anaesthesia by a qualified veterinarian. Desexing is a routine part of small animal practice across Australia, and when performed by an experienced team, it’s very safe.
The Health and Behavioural Benefits of Desexing Your Pet
There are many health and behavioural benefits to desexing cats and dogs, and this is where most of the conversation happens at the vet.
For female dogs and cats:
- Reduces the risk of mammary cancer. According to Agriculture Victoria, mammary cancer is fatal in 90% of cats and 50% of dogs. Desexing your pet before her first heat gives her the best chance of avoiding it. Female dogs desexed before their first heat cycle have as low as a 0.5% risk of developing mammary tumours, compared to 26% after a second heat, according to Lynbrook Vet.
- Prevents pyometra (uterine infections). Pyometra is a potentially life-threatening infection of the uterus that affects undesexed females. Research consistently shows that desexing significantly reduces this risk.
- Eliminates the risk of uterine or ovarian cancer.
- Prevents unwanted pregnancies. Dogs can fall pregnant from as early as six months of age, and female cats from around four months of age, according to RSPCA Australia.
For male dogs and cats:
- Eliminates the risk of testicular cancer.
- Reduces the risk of prostate problems as they age.
- Reduces roaming, urine marking, and aggression: Desexing also tends to make male pets calmer and less likely to wander in search of a mate.
- Reduces the risk of getting into fights with other animals, which can lead to serious injuries or infection.
For both sexes:
- Longer life. Research reviewed by Veterinary Partner found that desexed male and female dogs generally have slightly longer median lifespans than their intact counterparts, with spayed females living the longest overall.
- Desexing reduces the urge to roam, and that directly reduces the chance of being hit by a car or going missing.
- Fewer behavioural issues. The behaviour changes most pet owners notice after desexing are positive ones: less marking, less aggression, and a generally more settled temperament.
When Is the Right Time to Desex a Dog or Cat?
This is where things get a bit nuanced, and it’s why a conversation with your vet matters so much.
For cats (desexing your cat):
- Veterinarians generally recommend desexing your cat before her first heat, which typically occurs from around four months of age.
- Early age desexing (from 3 months) is well-established in Australian veterinary science and is commonly used in shelters and rescue settings. For most cats, an early age is the right time.
- Agriculture Victoria notes that early-age desexing is quicker and lower-risk, as the reproductive tract is smaller and blood vessels are less developed at this stage.
For dogs:
- The traditional recommendation is around five to six months of age, and this still holds true for many small to medium-sized breeds.
- For larger breeds, such as German Shepherds, Golden Retrievers, and Labradors, newer research suggests waiting until closer to skeletal maturity may reduce the risk of certain joint conditions. Your veterinarian will consider your dog’s breed, size, and individual health when making a recommendation.
- For a puppy of any size, the best thing you can do is ask your vet early so you’re working to a plan.
The key message: there’s no single answer that fits every pet. Talk to your vet about what’s right for your animal.
What to Expect: Before, During, and After the Desexing Surgery
BefreSurgery
- Your vet will recommend a pre-surgical wellness check: book one here at Keysborough Veterinary Practice to make sure your pet is healthy enough for anaesthesia.
- Pre-anaesthetic blood tests and imaging may be recommended, particularly for older pets or those with existing health conditions.
- You’ll be asked to fast your pet the night before surgery (no food from midnight is the standard guideline for most pets; your vet will confirm the specifics).
The Day of Surgery
- Your pet is admitted in the morning, and the procedure is performed under general anaesthesia.
- Most desexing surgeries are day procedures: your pet typically goes home the same afternoon.
- The team at Keysborough Veterinary Practice performs hundreds of desexing procedures each year across both dogs and cats.
Recovery at Home
- Your pet will come home with pain relief and clear instructions on post-op care.
- An e-collar (cone) will be needed to prevent your pet from licking the wound site. Yes, they’ll hate it, but it’s essential.
- Rest is essential for the first 10–14 days. No running, jumping, or rough play.
- A suture check is usually scheduled about 10 days post-surgery to make sure everything is healing well.
What’s normal: some grogginess the first night, mild swelling around the wound, reduced appetite for a day or two.
What to watch for: excessive swelling, discharge, persistent bleeding, or any signs your pet is in significant distress: call your vet straight away if you’re worried.
The Cost of Desexing vs. Not Desexing
It’s worth thinking about the cost of desexing in context. Treating a pyometra, managing a pregnancy and litter, or dealing with mammary cancer down the track will cost significantly more, not to mention the emotional toll. Desexing is genuinely one of the better long-term financial decisions you can make for your pet.
Council Registration Discounts in Greater Dandenong
Here’s a practical incentive that a lot of Keysborough pet owners don’t know about: the City of Greater Dandenong offers heavily discounted registration fees for desexed pets, and this discount applies for the life of your animal.
The Council is also a proud supporter of the AVA/MAV discount desexing voucher scheme: eligible concession card holders can collect a voucher and receive a 25% discount off normal desexing fees, with the Council contributing an additional set amount. Greaterdandenong

So, beyond the health benefits, desexing your pet literally saves you money on registration every single year. It’s a small thing, but it adds up.
Why Desexing Matters Beyond Your Own Pet
The bigger picture is worth a mention too. The RSPCA receives over 125,000 animals every year, and many of these are the result of unplanned breeding. In 2023–24, the RSPCA cared for 81,669 animals across Australia, and that number would be far higher without widespread desexing.
Every animal deserves to be loved and have a home to call their own. Desexing helps prevent unwanted animals from turning up at pounds, shelters, and rescue groups. RSPCA Queensland, along with The National Desexing Network, also offers referral services and vouchers for pet owners who may struggle with the cost of desexing.
Animal welfare is a community effort, and responsible pet ownership starts at home.

Frequently Asked Questions
At what age should I spay or neuter my dog or cat?
For cats, we generally recommend desexing from around four to five months of age, before their first heat cycle. For dogs, five to six months is generally suitable for most breeds, although larger breeds may benefit from waiting a little longer. Your veterinarian will provide a recommendation based on your pet’s breed and size.
Is desexing safe?
Yes, desexing is a routine procedure performed under general anaesthetic, and serious complications are uncommon. Your veterinarian will conduct pre-surgical checks beforehand to ensure your pet is in good health before undergoing the procedure.
Will desexing change my pet’s personality?
Not in a negative way. Most owners notice their pet becomes a bit calmer and less likely to roam or mark territory. Their core personality remains the same; they just tend to be more settled.
Does the City of Greater Dandenong offer cheaper registration for desexed pets?
Yes. Desexed pets attract significantly lower annual registration fees with the City of Greater Dandenong. It’s one of those practical benefits that quietly saves you money every year.
How long does recovery take after desexing surgery?
Most pets bounce back quickly, usually within a few days, and return to their normal selves. That said, you’ll need to keep them rested and wearing their e-collar for around 10–14 days while the wound heals, and schedule a quick suture check around the 10-day mark.
