Dogs do not need to be neutered when they are 8 years old. If the dog does not have any reproductive system diseases, it generally does not need to be neutered. Moreover, 8-year-old dogs are elderly dogs, and the functions of various organs in the body are gradually declining. Some dogs suffer from heart disease and respiratory diseases. General anesthesia may cause difficulty in breathing, heart failure, and even life-threatening conditions. Recovery after surgery is also slow, so sterilization surgery is not necessary.

Precautions for dog sterilization surgery:

1. Dogs need to eat and drink 8 hours in advance the day before the sterilization surgery, so as to avoid any discomfort during the surgery. The vomiting reaction during anesthesia causes food to flow back and cause the dog to suffocate.

2. Ensure that the dog’s vaccination is completed to prevent the dog from being more susceptible to viral diseases due to reduced resistance.

3. Before the dog is sterilized, a biochemical examination is required to evaluate the dog’s physical condition to avoid discomfort during the operation.
