Reasons not to spay a dog in heat:
- Increased risk of bleeding: The increased blood flow to the uterus during heat can make spaying more difficult and increase the risk of bleeding complications during and after surgery.
- Increased risk of infection: The cervix is normally closed during heat, which helps protect the uterus from infection. However, during heat, the cervix is slightly open and more susceptible to infection. This increased risk of infection can be exacerbated during surgery, and can lead to serious complications such as peritonitis.
- Increased anesthetic risks: Dogs in heat may have higher levels of certain hormones that can affect their response to anesthesia, increasing the risks of complications during surgery.
Generally, it is best to wait until after your dog's heat cycle has finished to have her spayed. This will help reduce the risks associated with spaying and ensure a successful surgery.
