| control reproduction | Avoid accidental breeding and reduce the number of stray animals |
| health benefits | Reduce the risk of reproductive system diseases, such as pyometra in female dogs, testicular cancer in male dogs, etc. |
| behavior improvement | Reduce behavioral problems such as territorial marking, aggression, and estrus anxiety |
| Extend life | Research shows that neutered dogs live 1-2 years longer on average than unneutered dogs |
2. The impact of neutering surgery on dogs
The impact of neutering surgery on dogs is multi-faceted, with both positive aspects and potential problems that need to be paid attention to.
| Impact type | positive impact | potential problems |

3. The best time for sterilization surgery
The choice of neutering time has a great impact on the health of dogs. Dogs of different breeds and genders may have different optimal neutering times.
| dog type | Recommended sterilization time | Things to note |
|---|---|---|
| Small dog (female) | 6-9 months | It is recommended to do this before the first heat |

| working dog/sporting dog | 18-24 months | Ensure adequate musculoskeletal development |
4. Preoperative preparation for sterilization surgery
To ensure that the surgery proceeds safely and smoothly, the owner needs to make the following preparations:
1. Preoperative physical examination: Make sure the dog is in good health and suitable for surgery
2. Fasting and water fasting: Usually fasting for 8-12 hours before surgery and water fasting for 2 hours
3. Prepare a comfortable rest area: you need a quiet recovery environment after surgery
4. Prepare the Elizabethan Circle: Prevent licking of wounds
5. Fully communicate with your veterinarian: Understand surgical risks and post-operative care
5. Key points of postoperative care
After spay/neuter surgery, good care is crucial to your dog's recovery.
| time stage | Nursing focus | Things to note |
|---|---|---|
| 24 hours after surgery | Close observation and restricted activities | Pay attention to anesthesia reactions and bleeding |
| 1-3 days | Wound care, taking medicine on time | Avoid licking wounds and keep them dry |
| 7-10 days | Gradual resumption of activities | Avoid strenuous exercise to prevent wound dehiscence |
| 2 weeks later | Review suture removal | Make sure the wound is completely healed |
6. Answers to frequently asked questions after sterilization

Q: Will neutering affect the dog’s personality?
A: Neutering mainly affects behaviors related to sex hormones, such as marking, estrus, etc. The basic personality will not change, and some dogs may become more docile.
