How To Prevent Pyometra In Dogs

If you are like other dog owners, you might be looking for how to prevent pyometra in dogs. You are reading the right post.

Pyometra is a regular problem in dogs. It occurs when the uterus becomes infected and fills with pus. This can be a life-threatening condition if not treated promptly. In this article, I will explain the causes, symptoms, and effects of pyometra in dogs.

What is Pyometra?

Pyometra is a serious infection of the uterus that can occur in dogs. The infection may be due to bacteria that enter the uterus through the vagina or through bacteria that are already present in the body. Pyometra can cause extensive damage to the uterus and lead to death if not treated. Treatment usually involves surgery to remove the infected uterus. Dogs that have had pyometra are at risk for developing it again, so they should be spayed.

The good news is that pyometra is a very preventable disease. I will break it down as you read on.

Types Of Pyometra In Dogs

There are two types of pyometra in dogs: open and closed. In an open pyometra, the cervix is open and the pus can drain from the uterus. A closed pyometra occurs when the cervix is tightly closed, trapping the pus inside the uterus. Closed pyometra is much more serious than open pyometra and can be life-threatening.

Causes Of Pyometra In Dogs

Bacterial Infection

One of the most common causes of pyometra is bacterial infection. This can happen when bacteria from the outside world enter the uterus through the vulva or vagina. The bacteria then multiply and cause an infection.

Some of the most common types of bacteria that can cause this type of infection include E. coli, Staphylococcus, and Streptococcus.

Hormonal Imbalance

Another possible cause of pyometra is a hormonal imbalance. This can happen when there is an overproduction of the hormone progesterone. Progesterone is responsible for preparing the uterus for pregnancy.

When there is too much of this hormone present, it can cause the lining of the uterus to thicken. This thickening provides the perfect environment for bacteria to grow and multiply, leading to an infection.


Tumors can also cause pyometra. These tumors can be benign or cancerous and can develop in either the ovaries or the uterus. While ovarian tumors are more common in younger dogs, uterine tumors are more likely to occur in older dogs. These tumors can cause an overproduction of progesterone, which can lead to a bacterial infection.

Immune System Disorder

Dogs with certain immune system disorders are also at risk for developing pyometra. These disorders can cause the body to produce antibodies that attack the normal cells of the uterus. This can lead to inflammation and an increased risk of infection.

Some of the most common immune system disorders that have been linked to pyometra include Cushing’s disease and diabetes mellitus.

Symptoms Of Pyometra In Dogs

Here are five common symptoms of pyometra in dogs:

1. Increased thirst and urination: One of the earliest signs of pyometra is an increase in thirst and urination. This is caused by toxins from the infection entering the bloodstream and causing kidney damage.

2. Lethargy and weakness: As the condition progresses, your dog may become increasingly lethargic and weak. She may also have a decreased appetite and lose weight.

3. Abnormal vaginal discharge: Another common symptom is abnormal vaginal discharge, which may be bloody or pus-like in appearance. If you notice this, it’s important to take your dog to the vet immediately as it’s a sign that the infection has progressed to the point where’s leaking out of the uterus.

4. Fever: A fever is another common sign of pyometra. The fever will usually be accompanied by other symptoms, such as increased thirst and urination, lethargy, and abnormal vaginal discharge.

5. Vomiting and diarrhea: In some cases, dogs with pyometra may also experience vomiting and diarrhea. This is a result of the infection spreading to other parts of the body.

How To Prevent Pyometra In Dogs

1. Spay your dog: The best way to prevent pyometra is to have your dog spayed (female dogs only). This simple surgery removes the ovaries and uterus, which eliminates the possibility of your dog ever developing this infection. If you have an unspayed female dog, talk to your veterinarian about the best time to spay her.

2. Keep your dog up-to-date on vaccinations: Vaccinations help to keep your dog’s immune system strong, which can help to prevent infections like pyometra. Be sure to talk to your veterinarian about the best vaccination schedule for your dog.

3. Keep your dog clean: Keeping your dog clean and free of dirt and debris can help to prevent infection. Be sure to brush your dog regularly and bathe her as needed.

4. Monitor your dog for signs of illness: It’s important to be aware of any changes in your dog’s health so that you can catch an infection like pyometra early. Signs of pyometra include increased thirst, urination, appetite, and lethargy. If you notice any of these signs, take your dog to the vet immediately.

5. Know the risks: Some things can increase your dog’s risk of developing pyometra, such as being overweight, having a retained heat cycle, or having had a previous uterine infection. Be sure to talk to your vet about any factors that may put your dog at risk so that you can be extra vigilant in monitoring her health.

What To Avoid Doing When Treating Your Dog From Pyometra

If your dog is diagnosed with a pyometra, it’s important to know what to do (and what not to do) to give your furry friend the best possible chance at a full recovery. Here are some things you should avoid doing when treating your dog for pyometra:

Don’t Delay Treatment

If your dog is diagnosed with a pyometra, it’s important to start treatment right away. Delaying treatment can allow the infection to progress and can lead to a life-threatening situation.

Don’t Give Your Dog Ibuprofen

Ibuprofen is a pain reliever that is sometimes given to dogs who are suffering from pyometra. However, ibuprofen can make the condition worse by causing more inflammation.

Don’t Ignore Symptoms

If you notice any of the following symptoms in your dog, please contact your veterinarian right away

By following these simple tips, you can help to prevent pyometra in your dog and keep her healthy and happy for many years to come.
