Preparation items before sterilizing dogs and cats:

1. Before surgery, make sure that the vaccine has been completed and has been administered for more than a week.

2. Sterilization surgery during estrus should be avoided, because the fragility of the uterus increases during estrus, and blood vessels increase and become thicker. Sterilization surgery at this time increases the risk of surgery.

3. It is best to make an appointment the day before the operation to avoid waiting too much time due to too many people and pets after entering the pet hospital, and causing unnecessary stress to the pets.

4. Generally, fasting is required for 6-8 hours and water is not allowed for 2 hours before surgery. This is to prevent vomiting during the operation, excessive abdominal pressure, and unnecessary difficulty in the operation.

5. Prepare an Elizabethan ring and put it on your pet after the operation to prevent them from licking the wound.

6. After entering the pet hospital, under normal circumstances, the doctor will recommend some examinations for your pet. It is very necessary to do a routine blood examination to measure the overall health of your pet from the white blood cells, red blood cells, and lymphocytes of the blood. A full set of biochemical examinations is also necessary to assess the animal's physical condition before anesthesia and reduce surgical risks.
