Ali Smith,

None of that appears to be a good suggestion when the potential penalties of those procedures are rumoured to be a number of the scariest ailments and illnesses a canine can face… Most cancers, Hip or Elbow Dysplasia, and different rotten afflictions like pyometra. All of that is the results of eradicating the supply of hormones…

Fortunately, analysis has come ahead which isn’t simply dimension particular, however breed-specific for 35 breeds! So, right here we’re going to debate the best instances for spaying or neutering your canine.

First, let’s perform a little housekeeping…

While neutering doesn’t have an effect on behaviour, neutering could have an effect on your boys roaming to search out females.

What’s Neutering?

That is the surgical castration of a male canine – normally by the removing of his testicles (sorry for making you cringe, gents!). This course of implies that your male canine can not breed and that they’re now not producing hormones which are necessary to your canine’s growth – each emotionally and bodily.

What’s Spaying?

Just like neutering, spaying is a type of surgical castration that removes the ovaries and most frequently the fallopian tubes together with it. This implies your woman can not breed, but it surely additionally means she is lacking some crucial hormones.

This course of could be finished in a ‘keyhole’ surgical procedure at further value, although it’s significantly better for restoration instances.

Really useful age:

Male – It’s your alternative!

Feminine – It’s your alternative!

With solely 94 St. bernards within the examine, it makes it actually troublesome to make use of this knowledge with any aspect of reliability. There’s not likely a large enough pattern of the breed to get reliability or trustworthiness in these numbers.

What Are The Dangers?

Right here’s a fast overview of what the examine says the breed suffers from relying on when their surgical castration (Spay or Neuter) was carried out. The purpose of offering this data is about providing you with all the knowledge to make the most effective determination.

Problems embrace – Cranial cruciate ligament tears or ruptures, Hip Dysplasia, Elbow Dysplasia 

Cancers embrace – LymphomaHemangiosarcomaMast Cell Tumours, Bone Most cancers (Osteosarcoma),

Gender Age of
Surgical Castration

Male Underneath 6 months 40% 17%
Male 6 to 11 months 14% 0%
Male 12 to 23 months 0% 0%
Male 2 years to eight years 0% 0%
Male Intact 8% 4%
Feminine Underneath 6 months 100% 0%
Feminine 6 to 11 months 0% 33%
Feminine 12 to 23 months 0% 0%

Feminine Intact 6% 11%
Comes from Aiding Resolution-Making on Age of Neutering for 35 Breeds of Canines: Related Joint Problems, Cancers, and Urinary Incontinence (Hart et al, 2020) the place 94 Saint Bernards have been monitored over the course of 15 years to gather this knowledge.
  • 15% of intact females developed Pyometra.
  • Urinary incontinence was not present in spayed females.
  • There have been no occurrences of Mammary Most cancers in both the intact or spayed females

So, there are a few points right here, such because the 100% of beneath 6 month previous females, and different spikes you possibly can see over this show.


I get that they give the impression of being scary, however please do keep in mind that the common pattern dimension for these canine is 10 canine – with a few of these ‘buckets’ solely containing 4 canine. Once more, with pattern sizes this small? We may actually be taking a look at one or two poor high quality breeders bucking these developments.

On this occasion, I’m hoping you acquire your canine from a accountable breeder, it might be greatest to return to your breeder and focus on this with them, they’ll (or ought to!) have knowledge on whether or not their woofs are having medical points and the way greatest to handle or keep away from them.

Please do keep in mind that well being testing is actually necessary! So earlier than you do put money into a pet, be sure your breeder has invested in them too, by trying on the Saint Bernard well being testing strategies from the OFA.

In the event you’re doing what I’m doing and taking a look at this analysis and reconsidering? It’s good to know that there are different choices obtainable.

Sure! On the presumption that these points are attributable to the shortage of hormones (which is nearly definitely the problem!) – there are a few methods to maintain hormones however not facilitate breeding.

For Ladies


That is the surgical removing of the uterus and solely half of the fallopian tubes! The removing of those implies that your woman is with out the power to breed – nonetheless – as she retains her ovaries, hormones will nonetheless be produced and will imply that her threat ranges are the identical as an intact feminine – with out the danger of pyometra! Although, there’s a threat that the breeding intuition can stay? Which can be fairly dangerous if a male tries to breed along with her.

For Boys


The tubes that run from the testes are known as the vas deferens – these are what get lower or eliminated on this occasion – rendering your canine with out the power to impregnate a feminine. It leaves his hormones (and certain his need to breed consequently) but additionally implies that your canine ought to have the identical threat elements as a whole male.

Chemical Castration

Do you know that surgical castration isn’t authorized in Norway? Consequently what’s widespread in Sweden, Denmark, and Norway is chemical castration which is an injection your canine should have each six months that drop the degrees of testosterone by roughly half. Which is confirmed to be efficient in short-term neuter in your canine. This implies you possibly can truly take a look at what castration may do to your canine and is commonly the way it’s used within the UK and America – but it surely’s additionally a unbelievable approach of not placing your canine via surgical procedures.

The examine “Aiding Resolution-Making on Age of Neutering for 35 Breeds of Canines: Related Joint Problems, Cancers, and Urinary Incontinence” (Hart BL, Hart LA, Thigpen AP, Willits NH) was launched in July 2020 – it covers 35 completely different breeds – and a separate scientific paper for blended breeds. The examine adopted a complete of 15,414 canine over 15 years of recording;

  1. The age of the canine when neutered or spayed
  2. Breed
  3. Problems together with: 
  4. Cancers together with;

Normal Ideas Throughout The Research

I discover it extremely fascinating that there’s breed-specific deviance. Previous to this, I used to be very a lot of the camp that it was merely a case of variations for canine of completely different dimension brackets – however that seems to not be the case.

For instance, a male Labrador (for whom I might have assumed weren’t dissimilar to a Saint Bernard) even have the most effective outcomes when neutered at 6 months – but the females choose a barely older age (When Ought to I Spay Or Neuter My Labrador is right here by the way in which!).

So it’s actually value doing all your analysis about these items.

As at all times? There’s not fairly sufficient data to make a very knowledgeable determination (yay for variables!) however, you possibly can positively get a good suggestion of it.

It’s value noting that this examine is a unbelievable guideline – and probably the most stable items of analysis we’ve had – it doesn’t bear in mind many elements that I would think about ought to be thought of. The restrictions I see are as follows;

  • A number of circumstances weren’t recorded in the event that they fell in the identical class,
  • Genetics weren’t thought of,
  • Residing circumstances weren’t thought of,
  • Meals high quality was not thought of,
  • The train a canine had was not thought of,
  • Physique situation was not factored in as a result of it had been studied beforehand and no sturdy correlation was discovered between physique situation and joint points.

The most important factor I can say is, that while that is the scientific advice for when to spay or neuter your St. Bernard do keep in mind that on the finish of the day? This is your determination. You’re the just one who could make this determination. So, do your greatest – you’ve already discovered an exceptional useful resource – simply maintain studying.
