Pymetra is an infection of the uterus. OVH is the removal the the uterus and and ovaries.
Pyomtera is a combination of a couple factors, an inappropriate response to the release of progesterone during a heat cycle and bacteria entering the body through the cervix and into the uterus. Once that process takes place, an increase of tissue growth starts (lining of the uterus thickens) causing cyst growth surrounded by pus/fluids. This usually happens to middle or older aged female dogs that have not been spayed.
The symptoms may or may not be obvious. If the cervix is open this allows for easier diagnosis, since the infected material (pus) can leave the body (Open Pyometra). If the cervix is fully closed (Closed pyometra), this is where it can be a bit more difficult to diagnose because the symptoms are insidious in nature.
Symptoms include vomiting, increase in urination and water consumption as well as decrease of appetite and depression. The more obvious sign would be the releasing of pus from the vulva in a female recently in heat but this is not always the case.
In order to diagnose a pyometra, the veterinarian would fully examine your pet, possibly request to perform blood workup(s), x-rays and an ultrasound.
If you suspect your female dog may have a pyometra, please do not hesitate to call (707) 745-5993 or come in. The longer you wait the more progressed the pyometra can become. If diagnosed with having a pyometra, supportive care (iv fluids and antibiotics) will be started and ultimately your pet will be spayed. Performing the spay removes the organ that is infected, which means very good prognosis for your pets’ health and quality of life.
