That might be a tabloid headline, though i guess it's pretty tame contrasted to "Elvis sighted in laundromat!" or "Politician actually admits lying!".  The suggest is the it's weird — dog who have actually been spayed have actually no uterus and also no ovaries, for this reason how can they quiet be having estrus cycles and also coming "in heat"?

Once upon a time, about 28 year ago, ns spayed a Scottish Terrier.  She continued to have actually heat cycles, and I was mystified (not to point out mortified).  the is NOT claimed to happen.

You are watching: Can spayed dogs still go into heat

Now, I have to tell you: when you're performing one ovario-hysterectomy top top a dog, occasionally it's pretty tough to traction the ovaries up out of the abdominal cavity.  If you're no careful, you can cut things a little close and leave part ovary in there.  as soon as you've reduced things off, you need to check what girlfriend removed and also be sure the totality ovary is over there (plus a small extra tissue, just to do you feel great about getting  100%). 

If friend leave some ovary in the dog, castle will proceed to bike regularly, coming in warmth every six months. Lock won't acquire pregnant, since you've eliminated the uterus, however they tho come in heat, they room still at higher risk for chest cancer, and also could also have "female trouble" arising pyometra in the stump the the uterus.

Sometimes, you reduced things pretty close, but in the instance of the above Scottish Terrier, ns recalled vividly the there had actually been no problems at all.  that was no a "close call".  So, I called the reproductive specialists to ask what I required to do.  currently you can run hormone assays to watch if over there is sensible ovarian organization left, yet if the dog is comes in warmth every six months, you deserve to be quite sure there is practical ovarian tissue.

Here's the problem: it could be a piece of ovarian organization the size of a pin-head.  The professional told me the I might even have actually implanted some ovarian cell on the body wall surface by rubbing the ovary against it ~ above the way out.  "Jeez, exactly how am ns going to find that?!" that told me come wait till she to be sure enough in heat (flaming) and also do one exploratory.  Look because that a small tiny red thing that looks prefer ovary. It can be all over — the proverbial needle in a  haystack.

So, what happened, you might ask?  The owners asked, "Can she acquire pregnant?" and when they discovered she can not, they refuse to enable the exploratory (even at my expense).  They chose to simply live through it, and the dog lived a long and also happy life, regardless of cycling every six months.  So, I'll never know if I might have discovered what I needed to.

This is Tinkerbell.  She was spayed at six months old, and at seven years old has had actually heat cycles every 6 months.  and also really, recently she hasn't been feeling all the great.  several years ago, ns told she owner what that would require to look because that the tiny tiny piece of ovary and also she chose not to perform it.  Lately, though it had actually started to bother both Tinkerbell and also her mom much more and more, so she said, "We'll perform it the following time she come in heat."

I must say that I had some misgivings.  I had told mommy that i wasn't certain I'd have the ability to find what us were looking for, even with the dog in heat.  It could be therefore tiny.  and also it could be everywhere in there… i thought.

What I had not counted upon was that whoever did her surgical procedure did an exceptionally lousy job… unbelievable, really.  This snapshot shows a item of ovary top top the right, gotten rid of from the usual ovary location.  top top the left, likewise attached come a usual ovary location, us have whole ovary, which you can't see due to the fact that it's behind that huge thing that looks prefer a Vienna Sausage.  The "thing" is a ar of uterus that is complete of pus, type of a pocket-sized pyometra. It was bigger 보다 her kidney or she colon, and also when I first looked in ~ it, i couldn't imagine what it was.  It just didn't take place to me that a surgeon can have left that lot uterus in place. 

So, while it was hard to believe, the wasn't every that hard to find.  I sent out the tissue off come the pathologist, reasoning it have to be a tumor or something, however it wasn't.  "Ovary and also uterus, filled v pus".  The great news is the Tinkerbell feels better than she has actually in a lengthy time.
