Old dogs need surgical treatment after suffering from pyometra. When diagnosed with pyometra, you should be hospitalized as soon as possible, because a closed uterus can easily cause rupture, which is life-threatening. If there is no intention to get the dog pregnant from the beginning, it is recommended to neuter the dog around one year old. This will not only prevent the dog from suffering from reproductive system diseases, but also reduce the trouble caused to the owner during the estrus process.

Notes on dog neutering:

1. Dogs of different sizes develop at different speeds, and the time for neutering will also be different. You have to wait until the dog is sterilized. Neutering can only begin after the dog is fully developed and sexually mature. It is generally recommended that dogs undergo neutering at 9 to 10 months.

2. Do not eat or drink 8 hours before the sterilization operation, and ensure that vaccinations are completed. Before the operation, a preoperative biochemical examination is required to evaluate whether the dog's physical condition can be sterilized. Surgery etc.

3. Do not let the dog lick the wound after the operation, because licking the wound by the dog will cause inflammation and swelling of the wound. If the dog bites the wound, it will have to be re-sutured. Therefore, the owner should wear the Elizabethan collar on the dog and do not let the dog take off the Elizabethan collar.
