Pyometra in pregnant dogs is a serious health issue that can have devastating consequences for both the mother and her unborn puppies.
Pyometra is a bacterial infection of the uterus that can cause a life-threatening buildup of pus.
Pregnant dogs are at higher risk of developing pyometra due to hormonal changes during pregnancy.
The risk of pyometra increases significantly after the 5th week of pregnancy.
A pyometra can rupture, leading to peritonitis, a potentially fatal infection of the abdominal cavity.
Symptoms of pyometra in pregnant dogs may include vomiting, diarrhea, lethargy, and abdominal pain.
If left untreated, pyometra can lead to sepsis, a potentially life-threatening condition.
Prompt veterinary attention is essential to prevent these complications and ensure the best possible outcome for the mother and her puppies.
Causes and Conditions
Pyometra in pregnant dogs can be a life-threatening condition, and understanding its causes and conditions is crucial for prompt treatment.
Pyometra is a bacterial infection that occurs when a dog's uterus becomes inflamed and filled with pus, often due to hormonal changes caused by pregnancy.
Chronic or persistent breeding can lead to a higher risk of developing pyometra, especially in older dogs.
A dog's age is a significant factor, as the risk of pyometra increases with age, with most cases occurring in dogs over 7 years old.
Prolonged heat cycles and repeated breeding can also contribute to the development of pyometra.
False Pregnancy (Pseudopregnancy)
False pregnancy, also known as pseudopregnancy, is a common condition in female dogs.
It occurs at the end of the heat cycle and can cause a range of symptoms, including weight gain and an enlarged abdomen.
Some dogs may even exhibit behavioral changes, such as acting as if they've given birth and refusing to eat.
Your veterinarian can diagnose false pregnancy by reviewing your dog's medical history, performing a physical examination, and taking x-rays or conducting an ultrasound.
Treatment is usually not necessary, as the condition typically resolves on its own within 1 to 3 weeks.
However, if your dog is uncomfortable due to milk production or is exhibiting troublesome behavior, your veterinarian may recommend treatment.
It's also important to avoid milking out your dog's mammary glands, as this can stimulate more milk production and make the condition worse.

Metritis
Metritis is a serious condition that can affect female dogs after pregnancy. It's usually caused by a bacterial infection, often from Escherichia coli bacteria.
Factors like prolonged or difficult delivery can increase the risk of metritis. Retained fetuses or placentas can also contribute to the condition.
The primary sign of infection is a pus-like discharge from the vulva. This is a clear indication that something's wrong.
Female dogs with metritis are often depressed or feverish. They may also have a reduced appetite and neglect their offspring.
Pups may become restless and cry incessantly if their mother has metritis. This can be a stressful time for both the mother and her puppies.
Treatment for metritis typically involves administering fluids, supportive care, and antibiotics. In some cases, medications may be given to expel a retained fetus or placenta.

Clinical Signs
Pyometra in pregnant dogs can be a serious condition, and it's essential to recognize the clinical signs to provide prompt treatment.
One key sign is the presence of pus draining from the uterus through the vagina, which can be noticeable on the skin or hair under the tail or on bedding and furniture where the dog has laid.
The dog's overall health can also be affected, with fever, lethargy, anorexia, and depression possible.
If the cervix is closed, the dog may become severely ill rapidly due to the buildup of pus and toxins in the uterus.
Anorexia, listlessness, and depression are common symptoms in these cases, and vomiting or diarrhea may also occur.
The toxins from the bacteria can affect the kidneys, leading to increased urine production and excessive water drinking.
