Don't wee on that!

Neutering is one of the most hotly debated topics in dog ownership. Everyone seems to have an opinion on it, from breeders and trainers to vets and fellow dog guardians. For years, neutering was often recommended as a blanket solution for a variety of behavioural challenges, but as our understanding of canine behaviour has evolved, so has the research on the effects of neutering.

So, what does the current evidence really say? Is neutering always the right choice, or are there situations where it may do more harm than good?

This blog explores the behavioural and medical implications of neutering, helping you make an informed decision based on your dog’s unique needs. By understanding how the procedure and hormonal changes can impact your dog’s behaviour, you’ll be equipped to decide what’s best for your companion.

Neutering and Behaviour: What We Know from Research

For years, neutering was widely believed to "solve" many undesirable behaviours, but the truth is more nuanced. Current research suggests that neutering may not always have the behavioural benefits people expect.

Here’s what the studies tell us:

Neutering male dogs during adolescence (a highly sensitive developmental period) can increase the likelihood of undesirable behaviours or even lead to the development of new issues, including aggression.
Neutering males and females has been linked to increased fear-based behaviours, heightened aggression, and, in some cases, early cognitive decline.

While neutering may reduce behaviours directly tied to reproduction, such as mounting, urine marking, and roaming, it has little or no effect on fear or aggression-related behaviours. In some cases, it can even exacerbate these issues, especially if fear is already present.

Neutering isn’t a one-size-fits-all solution for behavioural challenges. It’s important to understand the root cause of your dog’s behaviour before deciding if neutering is the right step.

Why Neutering Affects Behaviour

To understand why neutering can influence behaviour—both positively and negatively, we need to look at two key factors:

The Procedure Itself

Being neutered isn’t just a physical procedure for your dog; it’s a highly emotional and potentially stressful experience. Here’s why:

The veterinary environment can be overwhelming. Dogs are often left at the clinic, away from their caregiver, in a space filled with unfamiliar scents and sounds, including the pheromones of other anxious animals.
Pre-surgery handling (like restraint and injections) can trigger single-event learning, where a dog develops a negative association with unfamiliar people or handling. After surgery, this may result in fear-based behaviours, such as growling, fleeing, or even biting.

Hormonal and Physiological Changes

Hormones play a significant role in regulating your dog’s behaviour. When they are removed, the effects can vary depending on your dog’s temperament and emotional state:

Testosterone, often called a “confidence hormone,” can help reduce stress. Its sudden absence may lead to increased fear responses in some male dogs.
Oestrogens and progesterone, which influence social behaviours and resource sharing in females, are also lost during spaying. This can contribute to increased fear or resource guarding.
For adolescent dogs, behaviours like irritability may be caused by frustration. In these cases, neutering can help. However, if fear is a component of your dog’s behaviour, neutering may worsen the problem
It’s essential to assess your dog’s behaviour—ideally with the guidance of a professional trainer or behaviourist—before deciding to neuter.

Alternatives to Surgical Neutering

For dogs where neutering may worsen fear or aggression, temporary options are available to help you assess the potential behavioural impact:

Chemical castration involves using anti-testosterone medications like Tardak (short-term) or a Suprelorin implant (longer-lasting) to temporarily suppress hormones. This allows you to see how neutering might affect your dog without committing to a permanent procedure.

These alternatives are particularly helpful for adolescent dogs or those with existing fear or handling-related issues. Discuss these options with your vet if you’re unsure about proceeding with surgery.

Supporting Your Dog Before, During, and After Neutering

If you decide that neutering is the right choice for your dog, here are some tips to make the process as stress-free as possible:

Before the Procedure

Antianxiety medications: If your dog is highly anxious, ask your vet about prescribing the calming protocol for the day of the operation.
Desensitisation training: Prepare your dog for handling by practising gentle restraint and rewarding calm behaviour around strangers (like your vet).

After the Procedure

Collar alternatives: Many dogs find plastic “cones of shame” stressful. Consider a surgical garment or inflatable collar instead, as long as your dog can’t reach their wound.
Enrichment during recovery: Recovery often involves crate rest, which can be frustrating for dogs. Keep your pup mentally stimulated with low-impact enrichment activities like:
- Lickimats or stuffed Kongs
- Exploring the garden for new smells
- Treat trails or puzzle toys
- Bringing novel items (like pinecones or sticks) into the garden for your dog to investigate

These activities can reduce boredom and help your dog relax during recovery.

Neutering Female Dogs: Timing Matters

For bitches, timing the procedure correctly is critical:

Spaying should be done at the mid-point between seasons or at least 2-3 months after a heat cycle.
Spaying too soon after a season (during the dioestrus phase) can lead to sustained prolactin release, triggering “phantom pregnancy” behaviours such as resource guarding or social aggression.

This highlights the importance of discussing the timing of spaying with your vet to ensure it’s done at the safest and least disruptive time for your female dog.

Neutering: An Individualised Decision

Neutering is not a decision to rush into. Every dog is unique, and factors like age, breed, temperament, existing behavioural concerns, and size all play a role in whether neutering is appropriate.

Take the time to gather all the facts, consult with your vet and a qualified dog behaviourist, and consider your dog’s individual needs. In some cases, postponing neutering, or opting for alternatives like chemical castration, may be the best course of action.

Conclusion: Informed Decisions Lead to Better Outcomes

Neutering isn’t a simple fix for behavioural issues, and it’s not the right choice for every dog at every stage of life. By understanding the potential impacts, both behavioural and medical, you can make an informed decision that’s in your dog’s best interest.

If you’re considering neutering your dog and want guidance tailored to their individual needs, reach out for professional advice. Prevention and preparation are key to ensuring a smooth experience for you and your dog.
