The best time to neuter a male dog is before the first heat to prevent the dog from forming a permanent memory of the enclosure behavior during heat. Small dogs undergo surgery around 6 months to 8 months old. Large dogs grow relatively slowly, so it is recommended that surgery be performed around 1 year old. However, if the dog has passed the optimal age for neutering, it is recommended to do it as early as possible, because the older the dog, the higher the risk of anesthesia, and the postoperative recovery will be relatively slower.

Precautions for dog sterilization surgery:

1. Before the dog is sterilized, it needs to be vaccinated, the antibody level is good, and the liver is checked at the pet hospital. , kidney and heart examination, all indicators are normal before surgery can be performed.

2. Please note that no feeding is allowed before surgery. Do not feed or drink food to the dog 12 hours before the operation. Feeding will affect the anesthesia during the operation and may cause gastrointestinal motility to stop, flatulence or even more terrible consequences.

3. After sterilization, you must wear an Elizabethan ring to prevent the dog from licking and biting the wound, which may lead to wound infection.
