THERE’S a lot of debate when it comes to spaying and neutering pets, especially when it comes to behaviour changes.
Some people swear that fixing their dog or cat completely transformed their personality, while others claim it made no difference at all.
So, what are the facts? Does spaying or neutering really change a pet’s behaviour, or is it just another myth?
Verdict:
TRUE
First, let’s get one thing straight – spaying (for females) and neutering (for males) primarily serve medical and population control purposes.
They help prevent unwanted litters, reduce the risk of certain cancers, and can even increase a pet’s lifespan.
But behaviour? That’s where things get a little more complicated.
According to experts, spaying and neutering do influence certain behaviours, but not in the way some people expect.
One of the biggest myths is that fixing a pet will instantly make them calmer or more obedient.
In reality, procedures like these mainly reduce hormone-driven behaviours – think excessive marking, roaming, or mounting.
Studies, such as those published by PetMD and Psychology Today, show that neutered males are less likely to exhibit territorial urine marking and aggressive tendencies linked to testosterone.
However, it won’t magically turn a hyperactive dog into a couch potato or train them to sit and stay.
Similarly, for female dogs and cats, spaying eliminates heat cycles, which can reduce behaviours like yowling, restlessness, or attracting unwanted attention from potential mates.
Nonetheless, it won’t necessarily change a pet’s core personality.
A playful, energetic cat or pup before surgery is still going to be just as playful afterward.
Interestingly, timing also plays a role.
Research cited by the Chicago Veterinary Medical Association suggests that neutering at different life stages can have varied effects.
Dogs neutered before full maturity may show subtle shifts in behaviour, sometimes appearing more puppy-like for longer, while those neutered later might retain more dominant or territorial tendencies.
Of course, every pet is unique, and factors like training, environment, and genetics play just as big a role in behaviour as hormones do.
If a dog has behavioural issues such as anxiety or aggression, simply neutering or spaying won’t be a cure-all.
Training and socialisation are still key.
So, does a pet's behaviour change after spaying or neutering? The short answer: yes, but mostly when it comes to hormone-driven behaviours.
If you’re expecting a complete personality makeover, you might be disappointed.
Although, if you're looking to curb certain instinctual habits and promote a healthier, happier life for your pet, then spaying or neutering is absolutely the way to go.
