There is much talk today about having your pet spayed or neutered. Why should you as a pet owner consider this for your pet? Scientific studies have shown that spaying/neutering has many different benefits. It can help decrease your pet’s risk of cancer, reduce the occurrence of several disruptive behaviors and may even help your pet live longer. One benefit that is extremely important in females is the reduced risk of pyometra.
Pyometra is an infection within the uterus. This infection occurs due to the hormonal changes within an intact female. When the female is in heat, her body undergoes several changes to create an environment that is optimal for pregnancy. Her uterus will not allow white blood cells to enter to ensure that sperm is not killed by these white blood cells. She will also start secreting progesterone to increase the lining of the uterus so it could potentially support fetal development if she does become pregnant.
If the female does not become pregnant, she will start a new heat cycle. Over time as she keeps going through these cycles, her uterine lining will become much thicker and may eventually start making cysts. These cysts may start secreting a fluid that is a perfect environment for bacterial growth. Bacteria are able to enter the uterus when the female is in heat. During heat, the cervix (which acts like a gate to the uterus) is not tightly closed. The bacteria is then able to slip through the cervix and into the uterus, thus starting an infection.
Pyometra can make your female dog or cat very ill. This can also be very painful to your animal. If you spay your pet early enough you can prevent this horrible infection from ever occurring. A spay is an ovariohysterectomy which means that the uterus and ovaries are surgically removed, including the environment in which the pyometra causing bacteria thrive. In conclusion, eliminating the occurrence of pyometra is one of the many benefits to having your pet spayed.
