The dreaded dog spay?

June 29, 2007 / (5) comments


Yesterday’s surgery schedule was packed tight with the standard mix of routine, uneventful surgeries…at least, that’s what you might assume after reading this list:

  • Canine spay, medium
  • Feline dentistry/X-ray fractured tooth
  • Feline dentistry/apply sealant
  • Canine eyelid cyst removal/dentistry
  • Canine toe mass removal
  • Canine mass removal/re-check root canal
  • Canine spay, large/videoscope ears

Sure, there were seven cases, twelve procedures and only six hours before three PM (my “must-be-conscious-by” deadline). But this was doable. No stress. None, whatsoever…until I got into my first spay and saw she was in heat. Lots of careful manipulation later and…disaster averted.

So you know, dogs should not be in heat when they’re spayed—at least that’s my take on the subject. The blood vessels supplying the uterus and ovaries (the organs to be removed) are significantly increased in size, while the tissues to be handled are invariably more tender and susceptible to tearing.

(Unfortunately, you can’t always tell on the outside that a dog’s recently been in heat—and I like to wait a full month to give the tissues a chance to “settle.”)

IMHO, it’s not a safe situation, though many vets I’ve worked for in the past didn’t approve of my “no-spay-while-in-heat” rule. Their almost-universal rejoinder to my spay-postponement pleas? “If it’s on the schedule, you do it. Got it?”

(For the record, cats don’t qualify for postponement. Their procedure is far simpler, on average, than any dog spay.)

The next five cases went reasonably well, though the fractured tooth required extraction and the root canal’s opposite tooth required more of the same (scheduled for another day). Next up: the large dog spay. At the last minute, I decided to call the owner to ask when she’d last been in heat (that’s a standard receptionist question but it was the housekeeper who’d brought her in so I wanted to be sure). No answer. Oh well…

I was especially cautious about this case because she was eleven(!) years old. Now, we don’t see a lot of eleven year olds for spays, as you might imagine. If we do, it’s because they’re suffering from an allied ailment (infected uterus, mammary tumors, etc.). Most people willing to spay their dogs do so at a much earlier age. But there’s no cutoff limit—I’ll spay a dog at whatever age I have to just to get it done. Statistically, it’s always best for the dog’s health, regardless of age (as long as she’s in generally good shape).

Getting into this dog’s abdomen, though, I was reminded of why it is I’ve always hated large dog spays. Even when they’re not in heat, even when everything goes perfectly, there’s always a level of stress, sweat and suffering—and that’s just the vet’s side of things.

In spite of everything you might assume (given the artificially low price of this procedure and the apparent universality of its application), it’s a tough bit of work. Early on in my career I’d cry behind my mask and hope no one noticed. It seemed so hopeless, getting comfortable with something so difficult.

Yesterday, 45 minutes into the procedure (and I’m generally fast in my surgeries), I couldn’t help thinking: twelve years, hundreds of large dog spays and still I’m not comfortable.

Perhaps there’s a lesson here. Maybe there are some procedures no vet should ever get comfortable with.

Gil: When I say "statistically," of course that means the statistics we currently have available. Most of the research on spay incontinence is aimed at trying to find out 1) how prevalent it is and 2) what factors (age at spay, breed, weight, etc.) are involved. The goal is to come up with better recommendations for timing of spays, weight loss, drug therapy, etc. rather than prove spays are best not undertaken. That's because (in spite of the real problems of incontinence) pyometra, pregnancy complications and mammary tumors are far more dangerous to a dog's safety. There's ongoing research on longevity of spayed vs unspayed dogs and it sides markedly toward the spayed--however there are lots of confounding factors involved that are really hard to tease out. I promise to keep you posted on these but right now it seems like even the well-cared for bitch (with no pregnancies or pregnancy risk) lives longer when spayed.

"I’ll spay a dog at whatever age I have to just to get it done. Statistically, it’s always best for the dog’s health, regardless of age (as long as she’s in generally good shape)."

I never have bitches so this is just a matter of curiousity for me. "Statistically" it may be best for a bitch's health, but I've read any number of posts on spay incontinence, usually coming about, it seems, when a bitch is spayed too young. Realistically, you still think it's always best?

I am so happy that you wrote about this! Ever since my collie puppy Dixie was spayed at 6 months, I've been just beside myself whenever I think about it. I've had many cats spayed, and it never seemed to bother them at all. Most were running and jumping the next day.

When Dixie was spayed, she took so long to feel better. The night I brought her home she could barely walk, and she couldn't squat to pee. She wet her feet and just howled, and I had to carry her back inside. After that, she stayed immobile in her crate for three more days- I fed her with a spoon, and cried nearly non-stop. It wasn't till after I kept calling back that a tech returned my calls and told me that sometimes large dogs have a harder time with the procedure. It seems they don't like to alarm owners ahead of time for fear they won't have the spay done. I signed a contract with my breeder and would have had her spayed no matter what, but knowing what to expect would have helped me a lot.

I think the thing I most love about your blog is that you say things I wish my own vet would tell me. He's wonderful and he'll talk about anything if I bring it up, but sometimes I don't know what to ask in the first place. Thanks for this article.

My vet charges more for spays on dogs or cats that are in heat prior to surgery because of the risks involved. When the owners of the older pets start complaining, she raises her right eye brow and asks "Well. why didn't you have {insert name here} in the first place, instead of waiting until {insert time frame here}? These owners start rattling off their "excuses" and she just watches them squirm and waits for their motor mouths to become silent.

Once they shut up, she explains the procedure and what will happen when the pet is sent home the next day, problems to watch out for, ect.
