Spay: removing just the ovaries vs. removing just the uterus

Jaquie & Starbuck

Well-Known Member
My vet wanted to spay Starbuck in the next month. She's now 5 months old and I've decided to look for a new vet, someone who agrees it can be better for giant breeds to wait to spay until at least 18 months.
I've found a holistic vet in my area, and she performs a different kind of spay that I had never heard of before; I'd like your opinions.
My last vet only performs the traditional ovariohysterectomy, removing everything. My new vet offers different options. She will either remove the ovaries, leaving the uterus, which eliminates heats but is a less extreme surgical option than ovariohysterectomy. Or she will do the opposite; remove the uterus and leave the ovaries. Apparently, the dog will still experience heats with the latter option, but will have no bleeding, and no screwing up hormones.

Has anyone heard of this? Here's what the vet emailed to me:

"I will be offering a new kind of spay for those that think it is best for their pets, with my guidance of course. It apparently is only offered by 3 veterinarians in the U.S. right now. Basically, it involves leaving the ovaries in, but removing the whole uterus. Of course, this is called a hysterectomy and has been done for a long time in women. However, the problem for animals is that, if you leave the ovaries in, but leave any remnant of the uterus behind, the risk that the animal will get an infection in the little leftover uterus bit is high, called Pyometra. We don't want this, so the idea is to eliminate this risk by removing the entire uterus.

Right now and for years now I have been removing only the ovaries which eliminates the heat cycle and all risk of pyometra, the pus-filled uterus, plus we try to optimize the timing of the spay or neuter. Spaying also eliminates the risk of mammary tumours, depending on the age of spay. Because there is mounting evidence that suggests it is not always the best thing to spay and/or neuter your dog, especially large breeds, due to the increased risk of various cancers like bone cancer, obesity, torn ACL's, urinary incontinence, etc, this new type of spay may be just the answer for some people.
Here is a link to a paper for those so inclined to research and here is a link to the site that has a video of the partial spay surgery. The dog will still experience heat cycles and she will still have the benefit of the hormone protection, but won't be able to get pregnant, no bleeding and no risk of pyometra. I now have personal experience with this latter issue as my 10 year old completely intact Kira has developed Pyo just this past weekend! So spayed she is now and, unfortunately, it also appears that at her surgery one ovary is abnormal and may be cancerous, which is highly unusual in dogs....results pending. Send her good thoughts...

Up to now, what I have been counseling my clients with puppies to do is thus:


a. Dogs under 50 lbs: Spay or neuter not sooner than 7.5 months and waiting until they reach 1 year is fine too.

b. Anything over 50 lbs: Wait until 14 months or older (means the females go through one full heat cycle)

c. Cats: Still best to do at about 5-6 months old


Now I will start offering the partial spay at a younger age for those that want the dog to keep the ovaries for all the benefits that entails and don't mind the heat cycles, but don't want to risk an accidental pregnancy on the first heat.


I don't wish to go into all the pros and cons in this newsletter as it is too much of a discussion. What I want you to go away with is that it is no longer considered best for all animals to be have a full ovariohysterectomy by 6 months and may in fact be detrimental to the long term health. If you want more information on this as well as the pros and cons of neutering your male dogs and best timing, please schedule an appointment and we can talk further. So many options!!"

Here are a couple of links that I found very useful for information about spay:
"Determining optimal age to spay or neuter your pet": http://www.imom.org/spay-neuter/pdf/kustritz.pdf
"The spay and neuter conundrum": http://www.pawsitivevetcare.com/the-spayneuter-conundrum-long-version/

I definitely welcome feedback!!

Jaquie.

Interesting read. I've never owned a female so I cannot offer any feedback. Hopefully, the female owners will post a reply.

Removing the uterus and not the ovaries could be problematic. How will the body shed the eggs when they drop? But leaving them in will allow the estrogen to be produced. Removing just the ovaries will remove the production of the hormones. I don't know what I would do.

Depending on the reason for a hysterectomy, many women are left with their ovaries. I don't think I'd be concerned about the eggs. I would assume that they get reabsorbed. I would be more concerned about stump pyometra. I'm going over my own options as Ella approaches her second birthday.

I'm a little late to the party here, but we had an ovary sparing hysterectomy performed on Molly our bullmastiff. We spoke with Dr. Michelle Kutzler who developed the technique and were convinced to leave the ovaries. The links above point to some very convincing articles on leaving the sex hormones intact. Here is an interview with the good doctor - a little long but some good info to help you with your decision.. http://http://healthypets.mercola.com/sites/healthypets/archive/2013/09/23/modified-spay-procedure.aspx

Wow I so love that someone has stepped outside the box and considered the health of the breed rather than just desex and be done with it.

Update: Starbuck is now 15 months old. She hasn't had her first heat yet, but we went to Pawsitive Vet Clinic today and had the ovary-sparing spay. The procedure went well, and Miss Starbuck has been sleeping all day. She's a little wobbly but of course that's to be expected.

Kind of neat; I actually got to watch the procedure today. Very interesting (and a little emotional).

Thanks everyone for the comments. I'm hoping she has a quick recovery.

I just found this thread and I was wondering how the dogs are doing who had the partial spay. We have a 5 month old English Mastiff and are looking into this option. Does your dog bleed at all when they are in heat? And are there any other issues when they are heat?

Hi tlov! I did end up going this route with Starbuck and I am glad we did. We did her ovary sparing spay back in January at a holistic vet. Starbuck was 15 months old and had not been through heat when we had the surgery. The surgery is a little more invasive, just because they have to dog around in there a bit more to remove the entire uterus and leave one ovary in tact. We did not need a cone for her. Looking back, she was back to her normal self about in a week I think. She has since gone through heat. Her vulva swelled up like an apple and you could tell she was like "Wtf is going on with my rear end?!". There was no blood at all, but one day where she had a little bit of discharge. Literally only once, and about a tablespoon. She was money and quiet while in heat. Her nipples are bigger than they were before but other than that no difference. She is still growing now at 20 months old, and is filling out beautifully. I am glad we decided to keep an ovary. Let me know if you have any other questions, I'm happy to answer them.

the advantage to removing the ovaries only , i think is the ease of recovery , i found it actually impressively easy , it was like a minor surgery .............. as far as leaving the ovaries , imo , any advantages are yet to be proven . 2002 is not that long ago , we just recently lost a neutered dogue born in 2002 , i've been spaying bitches since 1979 and have yet to have a bone cancer or torn acl in a bitch......... i'm sure time will tell if it's healthier to leave a non-breeding bitch intact .........

I scheduled the ovary sparing spay. We bought our EM with a pet contract and we have to have her spayed by the time she is 8 months old. I didn't think anything of that at the time because we have no interest in breeding her. Now that I've been reading more about giant breeds I don't feel it would be best to do a traditional spay on her this young. Hopefully I'm making the right decision. Also we have a Bassett Hound that has been on medication for incontinence for years. After all the research I've done lately I think that is probably due to us having her spayed young, but of course there's no way to know for sure.

Our Molly just turned 2 and she has (we think) stopped growing. We are so glad we spared her ovaries. She has been so healthy and active. Her heats have produced just a little discharge. She has large nipples!

We put our vet in touch with another vet so he could do the procedure - now they routinely do ovary sparing procedures - especially for large breeds. Many countries in Europe have outlawed removing gonadal material from dogs because of the increased health risks.

There are several good links from the website I put in my original post to read about the research for keeping sex hormone producing tissues.
