Desexing Facts
 

Responsible Ownership • Informed Choices • Animal Welfare

Desexing (spaying or neutering) plays an important role in responsible pet ownership and animal welfare. While it is not a one-size-fits-all decision, desexing is widely recognised as one of the most effective tools for preventing unplanned litters and reducing the number of dogs and cats entering pounds and shelters.

Pet overpopulation remains a real and ongoing issue. Every year in Australia, tens of thousands of dogs and cats enter shelters, and sadly many are euthanased due to lack of space, resources, or suitable homes. Preventing unplanned breeding is a key part of reducing this burden and improving overall animal welfare.

Desexing is not about taking something away from your pet — it is about making informed, responsible choices that support their health, behaviour, and quality of life, while also helping the broader animal community.

​

Why Desexing Matters

Desexing dogs and cats is widely promoted by veterinary and animal welfare organisations as one of the most effective methods of population control. When pets cannot reproduce, fewer unwanted puppies and kittens are born, and fewer animals end up in shelters or face euthanasia.

Responsible breeding should always be intentional, planned, and based on health, temperament, and purpose — not accidental.
 

Common Myths About Desexing

​

Myth #1: “My dog will feel like less of a ‘man’ or ‘woman’ after being desexed”

Dogs do not have a human sense of identity tied to reproduction. They do not experience loss, shame, or reduced self-worth from being desexed.

A dog’s personality is shaped primarily by genetics, early development, environment, and learning — not by sex hormones alone. Desexing does not remove your dog’s individuality, confidence, or ability to bond with their family. It simply removes hormone-driven reproductive urges that your dog has no way to satisfy in a pet environment.

Myth #2: “Desexing will make my dog fat”

Desexing does not automatically cause weight gain, but it can increase the risk if diet and exercise are not adjusted.

After desexing, some dogs have slightly lower energy requirements and increased appetite. Weight gain occurs when calorie intake exceeds energy use — not because of the surgery itself. Maintaining a healthy body condition is achieved through:

• Appropriate portion control

• Regular exercise

• Monitoring body condition score

With responsible management, desexed dogs can remain fit, lean, and active throughout their lives.

Myth #3: “Dogs mourn the loss of their reproductive abilities”

Dogs do not reproduce for emotional reasons or family bonding. Male dogs do not recognise puppies as their own, and female dogs do not experience grief over not having litters.

In the wild, reproduction serves species survival — not emotional fulfilment. In a domestic setting, removing reproductive capability simply removes a biological drive that cannot be ethically or practically fulfilled.

 

Myth #4: “Desexing is too expensive”

Desexing is a once-off procedure and is often far less costly than the long-term expenses associated with:

• Pregnancy and whelping complications

• Emergency caesareans

• Pyometra (life-threatening uterine infection)

• Injuries from roaming, fighting, or mating behaviours

• Raising and rehoming unplanned litters

For those experiencing financial hardship, assistance programs are available in Australia, such as the National Desexing Network (NDN), which helps eligible owners access discounted desexing services through participating veterinarians.

Health Considerations of Desexing

Desexing is associated with both benefits and considerations, and the best timing may vary depending on breed, size, sex, and individual health.

​

Females

Desexing:

• Eliminates the risk of pyometra, a serious and often fatal uterine infection

• Prevents ovarian diseases (tumours or cysts)

• Prevents false pregnancies

• Removes the physical strain associated with repeated or unplanned breeding

There is evidence that spaying may reduce the risk of mammary tumours, though modern research shows the strength of this effect varies and is less definitive than once believed. Timing and individual risk factors matter.

Males

Desexing:

• Eliminates the risk of testicular cancer

• Greatly reduces hormone-driven prostate enlargement and related disorders

• Can reduce roaming and mating-driven behaviours

Some studies suggest altered cancer risks in desexed males depending on breed and timing, which is why desexing decisions should always be discussed with a veterinarian who understands breed-specific considerations.

​

Behavioural Effects

Desexing can reduce behaviours that are strongly influenced by reproductive hormones, including:

• Roaming in search of a mate

• Urine marking

• Mounting behaviour

• Some forms of male–male competition

However, desexing is not a cure-all for behavioural issues. Fear-based aggression, anxiety, and learned behaviours require appropriate training, management, and sometimes professional behaviour support. Desexing works best as part of a holistic approach to responsible ownership.

​

Cost & Community Impact

Desexing:

• Reduces the number of unwanted animals entering shelters

• Lowers the emotional and financial burden on rescue organisations and councils

• Prevents the ethical and legal consequences of abandoning animals

• Saves owners from the cost of caring for unexpected litters

• Reduces the likelihood of costly injuries caused by roaming or fighting

Preventing unwanted litters is far more humane — and far less costly — than dealing with the consequences after the fact.

A Balanced, Responsible Approach

At Ukeevea, we support informed, evidence-based decision-making. Desexing is a valuable tool in responsible pet ownership, but timing and suitability should always be discussed with a qualified veterinarian who understands your dog’s breed, size, and individual development.

Responsible ownership means:

• Preventing unplanned breeding

• Prioritising health and welfare

• Making decisions based on facts — not myths
