What Is The Best Age To Neuter A Corgi

Updated November 28, 2020

Whether you call it neuter, spay, castrate or desex, there’s been a lot of debate about the right time to get it done in dogs. That’s because it varies from breed to breed. Recently, a study was published on the best age for neutering in Corgis.

While the paper isn’t perfect (more on that later), it does provide the first evidence for Corgis on choosing a time of desexing with the fewest health problems. The study compared dogs neutered at different ages for their rates of:

All of these have been suspected to be linked with the age of neutering. Here’s what they found (only bold values are significant, my summary to follow):

Summary: The Best Corgi Spay & Neuter Times

There is minimal evidence that Corgi joint problems or cancer rates are influenced by the age of neutering. However, four males who were desexed under 6 months of age were diagnosed with intervertebral disc disease, and there is good evidence from Dachshunds that IVDD is more common with early desexing.

Recommendation: between 6 and 12 months for both sexes, but the decision may be based on other factors such as:

Problems With This Study

In the original paper, the authors appear to make some recommendations based on very limited evidence. I have published the original study data so you can see the actual numbers involved and decide for yourself.

The authors also do not mention the well-known increase in lifespan associated with desexing male and female dogs, which tends to counteract most concerns about specific cancers. The following comment in the paper is a clue that it might also have been true for this population:

Across all breeds the mean age of last entry in the record for neutered males was 5.5 years (range 3.71–6.54), for neutered females 5.7 years (range 4.21–6.97), for intact males 4.9 (range 4.15–7.11), and intact females 4.7 (range 3.41–6.32)

The study tries to also look at the rates of mammary cancer & pyometra in females, but cannot give an accurate assessment for two reasons:

  1. the mean ages listed above are far too young to pick up most cases
  2. pyometra and mammary cancer are rarely referred to university hospitals

Regardless of any concerns, the authors are to be applauded to bringing into focus one of the most common questions from dog owners. For the Corgi at least, they’ve made the decision a lot easier.

  1. Hello,
    I have a 9 month old Corgi.
    At 5 months we believe he flew over 5 steps.
    Started limping, took to vet, said it was growing pains.
    Limp continued, took again, given anti inflammatory and pain med.
    Limp continued, xrays were sent to radiologist, coronoid disease.
    Limp continued, referred to surgeon, who now says it’s a chipped
    Cost for surgery is 4000.00. Very expensive.
    Do I need to get a 3rd opinion?
    What should I do?
    Thank you

    1. Hi Ceci. In cases where two veterinarians have different opinions, it’s worth getting a third from a registered specialist (if either of the current two are not). Bear in mind that in a corgi, elbow disease is common. Two possibilities are elbow incongruency or angular limb deformity. Good luck.
