Swelling usually subsides in 3-5 days after a dog is neutered. Slight redness and swelling at the surgical site after sterilization surgery are normal. Anti-inflammatory drugs can be taken orally or injected for 3-5 days after the surgery. Iodine or lysozyme spray can be used at the surgical site to prevent secondary bacterial infection. The surgical site should be kept dry, and the owner must wear a collar on the dog to prevent licking and biting. If the wound is still red and swollen seven days after the operation or if there are symptoms such as gradually increasing swelling, suppuration and infection, you should take the dog to the pet hospital for treatment in time.

Precautions for dog sterilization:

1. Pay attention to the choice of anesthetic. Anesthesia during surgery is generally divided into injection anesthesia and respiratory anesthesia. Injection anesthesia means that the doctor uses an injection to anesthetize the dog according to the pet's weight. The disadvantage is that if the amount of anesthesia is not calculated clearly, it may be difficult for the dog to wake up and lead to death. Respiratory anesthesia allows you to remove the respirator immediately when the operation needs to be stopped. The disadvantage is that it is more expensive.

2. Pay attention to transportation vehicles. After the dog's surgery, there will be a period of about 20 minutes for the anesthesia to wear off. During this period, the doctor will determine whether the pet can go home based on the degree of recovery. Because the anesthesia cannot completely withdraw and the pet is still unsteady, it is recommended that the owner choose Cars, a convenient means of transportation for dogs to rest, take them home.

3. Be careful not to go into a dirty environment after returning home. It is certain that there will be surgical scars after the operation. At this time, the owner should wear an Elizabethan collar on the dog to prevent them from licking, and remember not to take them to play in a dirty environment to avoid wound infection.
