When Is the Right Age to Desex Your Pet?

Why There’s No One-Size-Fits-All Answer

One of the most common questions we’re asked is when the right age is to desex a pet. In this video, Dr Ebeneze from Takurua Vets explains why there is no single “perfect” age, and how the answer depends on your pet’s species, breed, sex, lifestyle, and individual risk profile.

Decisions around desexing involve balancing cancer risk, bone and joint development, hormone-driven behaviours, and the very real risk of unwanted pregnancies. This guide explains how vets weigh these factors and why an individualised approach leads to the best outcomes.

Hello, I’m Dr Ebeneze from Takurua Vets. One of the most common questions we get asked is when the right age is to desex a pet.

Unfortunately, there’s no blanket answer. There’s no single perfect age. Cats and dogs, males and females, small breeds and large breeds all have very different risk profiles.

When we talk about the right timing, we’re weighing up things like cancer risk, bone and joint development, hormone-driven behaviours, and the very real risk of unwanted pregnancies.

In some animals — like cats that are going to be outdoor cats — it can be beneficial to desex earlier. In others, particularly large and giant breed dogs, it may be better to wait a little longer, often until around one and a half to two years of age.

The most important thing is that every pet is different and every situation is different. Desexing decisions should be individualised and discussed with your vet to determine the right timing for your pet.
