The most painful time for a dog after a sterilization operation is generally 1-2 hours after the operation. At this time, the anesthetic is basically ineffective, and the dog may become agitated, bark, and other behaviors due to pain, and the dog may lick the wound due to pain, so the dog needs to wear an Elizabethan ring. During the postoperative recovery period, the owner needs to use antibacterial and anti-inflammatory drugs on time every day to prevent secondary infection, and also needs to use saprophytic and myogenic drugs to promote wound healing.

What should you pay attention to after the dog has been sterilized:

1. 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 inflammation and infection.

2. Pay attention to nutritional supplements. During the recovery process from surgery, the dog will be weak and may have a loss of appetite. During the recovery stage, the dog should be properly supplemented with nutrients. If it does not drink water or eat, you can use a small syringe to feed it into its mouth.

3. Please note that you can only drink water eight hours after surgery. If a dog drinks water soon after the sterilization operation, it may lead to the risk of intestinal torsion or obstruction, so the owner must remember to give the dog water 8 hours after the operation.
