Infected Uterus in Dogs: Congratulations, It’s a Pyometra—Miku’s Story

Pyometra is a life-threatening bacterial infection in the uterus of dogs. 

Infected Uterus in Dogs: Congratulations, It's a Pyometra—Miku's Story

Miku is a female Akita, about seven years old. My friend is “babysitting” her—kind of. The exact circumstances aren’t that important.

Miku’s story

The whole story started with my friend asking how long a heat cycle should last.

I have to admit I know very little about these things because I never had an intact dog. And given our plan to only adopt or foster adult dogs from now on, the odds of having one in the future are low.

Generally, the heat cycle lasts between 2-4 weeks. That’s all I know, and I had to look it up.

I asked the friend why she wanted to know.

Miku continues to bleed after her heat cycle

“I think she’s bleeding longer than she should,” the friend replied.

Since it hadn’t been over four weeks yet, the friend was satisfied that it might still be expected.

Another week later, I got another inquiry about Miku. She was becoming increasingly picky with her food and would accept only the most attractive items. I was asked whether it could still be from not feeling well due to the cycle.

While I suppose that could be possible, I felt that the heat should have been over by then.

Miku loses appetite

I noted that a dog that doesn’t want their food is usually a concern to me.

Even though Miku had some history of being a finicky eater, this was a turn for the worse even from that. I recommended the owner be notified, and Miku was brought to a vet for a good “look over” and some labs.

The owner, however, didn’t believe there was a problem.

A few days later, Miku not only didn’t want to eat but wasn’t even interested in anybody coming out to see her.

Miku gets lethargic

Miku was always inside out every time anybody showed up.

But now, she wouldn’t come up to greet. So this time, I insisted something was wrong for sure, and Miku needed to be seen.

Pyometra concern

The most dangerous thing that can make a dog start acting sick after coming out of heat is an infection of the uterus, pyometra.

“I do not want to scare you,” I said, “but this would be my primary concern. And I explained to her what pyometra is. “I hope I’m wrong, but Miku should really see a vet to at least rule this out.”

Pyometra can be life-threatening. If that is what’s going on, it calls for prompt action.

Veterinary visit

It took Miku becoming severely lethargic for her owner to finally take her into a clinic.

Later that day, my friend reported that the vet said it was a minor infection, and Miku got sent home with antibiotics.

A mild infection? Of what? Having three degrees of separation between myself and the vet, I wasn’t going to be getting more detailed information. Indeed the vet would have thought of and ruled out pyometra before just sending Miku home with a bottle of antibiotics?

Not pyometra after all?

I figured I was wrong about it which would have been great.

Once on the antibiotics, Miku did start looking better. So maybe it was some kind of a “mild infection,” whatever that kind of diagnosis meant. However, I did find it very strange for a dog to act so sick just because of a mild infection.

Miku finished her medications a seemed to have been in better shape. She even got more interested in food.

Miku is still not well

Yet another week later, it turned out she was still discharging.

And her appetite and energy level were sinking again. “The owner is taking her back to the vet to be spayed,” my friend updated me.

Finally, a diagnosis

Miku was dropped off in the morning for her surgery expected to return home the same day.

Instead, she remained in the hospital for IV and intensive care.

“Her uterus was twice the size of a normal one,” the vet relayed, “I’ve never seen uterus this big.”

Funny, I have. Though, fortunately, only on photos and videos. I’ve seen uteri much larger than twice the normal size, full of pus.

It was pyometra

Miku was suffering from pyometra after all.

I do hate being right. But I’m glad that Miku finally got the intervention she needed. I’m so happy I kept pushing the matter.

Miku did recover, and she’s doing better now than ever.

How close did Miku get to getting deathly ill?

Pretty damn close.

While I believe dogs should not be spayed or neutered as early as many vets still promote, I also believe they should definitely get “fixed” by the age of two or less, depending on the breed. Unless science comes up with a reason why they shouldn’t be “fixed” at all.

Most importantly, though, please remember this:

Consideration for intact female dogs

If your intact female dog starts acting sick after the end of the cycle, please, think pyometra.

If it’s not, the better. But if it is, acting early can be life-saving.

“I can’t believe she’s still alive,” Miku’s vet said.

I can’t believe the vet didn’t suspect pyometra the first time Miku was in her clinic.

All is well that ends well, though if everybody did things just a little differently, it could have saved Miku quite a long time of suffering.

I am a graphic designer, dog health advocate, writer, and author. Jasmine, the Rottweiler of my life, was the largest female from her litter. We thought we were getting a healthy dog. Getting a puppy from a backyard breeder was our first mistake. Countless veterinary visits without a diagnosis or useful treatment later, I realized that I had to take Jasmine's health care in my own hands. I learned the hard way that merely seeing a vet is not always enough. There is more to finding a good vet than finding the closest clinic down the street. And, sadly, there is more to advocating for your dog's health than visiting a veterinarian. It should be enough, but it often is not. With Jasmine, it took five years to get a diagnosis. Unfortunately, other problems had snowballed for that in the meantime. Jasmine's health challenges became a crash course in understanding dog health issues and how to go about getting a proper diagnosis and treatment. I had to learn, and I had to learn fast. Helping others through my challenges and experience has become my mission and Jasmine's legacy. I now try to help people how to recognize and understand signs of illness in their dogs, how to work with their veterinarian, and when to seek a second opinion. My goal is to save others the steep curve of having to learn things the hard way as I did. That is the mission behind my blog and behind my writing. That is why I wrote Symptoms to Watch for in Your Dog, which has turned out being an award-winning guide to dog owners. What I'm trying to share encompasses 20 years of experience.
