When it comes to the care of a female Shih Tzu, one of the most significant decisions a pet owner must make is determining the best age for spaying. This article aims to shed light on the veterinarian consensus regarding the appropriate age for this procedure, while also discussing the pros and cons of spaying at different ages. Additionally, we will explore alternative methods to traditional spaying.

1. Introduction to Spaying in Shih Tzus

Spaying, or ovariohysterectomy, is a surgical procedure involving the removal of a female dog’s reproductive organs. For Shih Tzus, a breed known for their distinct personality and specific health needs, this decision is particularly crucial.

2. Veterinarian Consensus on Spaying Age

Most veterinarians recommend spaying female Shih Tzus between 6 to 9 months of age, ideally before their first heat cycle. This timing is advised to minimize health risks related to the reproductive system and prevent unwanted pregnancies.

3. Advantages of Early Spaying

Spaying a Shih Tzu before her first heat cycle significantly reduces the risk of mammary tumors and eliminates the risk of ovarian and uterine cancers. It also prevents unwanted pregnancies and can mitigate certain behaviors associated with the heat cycle, such as aggressiveness or marking.

4. Disadvantages of Early Spaying

Early spaying can potentially increase the risk of certain health issues. In Shih Tzus, these risks may include urinary incontinence and a higher likelihood of developing obesity. Moreover, early spaying may impact the development of bones and joints, though this is less of a concern in smaller breeds like Shih Tzus.

5. Advantages of Later Spaying

Spaying after the first heat cycle allows the Shih Tzu to reach physical maturity, which can be beneficial for their overall development. It may also reduce the risk of certain orthopedic problems and urinary incontinence.

6. Disadvantages of Later Spaying

The main downside of delaying spaying in Shih Tzus is an increased risk of mammary tumors and pyometra, a severe uterine infection. Each subsequent heat cycle raises the risk of these conditions. Additionally, there are the potential complications associated with pregnancy and birthing.

7. Alternatives to Traditional Spaying

Given the pros and cons of early and late spaying, some Shih Tzu owners consider alternatives. Ovary-sparing spay (OSS) leaves the ovaries intact while removing the uterus, reducing some health risks while preventing pregnancy. Laparoscopic spay, a less invasive method, is another option offering quicker recovery.

8. Special Considerations for Shih Tzus

When deciding on the best age to spay your Shih Tzu, consider the breed’s specific health predispositions and your dog’s individual health status. Consulting with a veterinarian familiar with small breeds like Shih Tzus is crucial for a decision tailored to your dog’s needs.

9. Post-Spaying Care for Shih Tzus

After spaying, it’s essential to provide appropriate care for your Shih Tzu. This includes managing pain, preventing the dog from licking or biting the incision site, and watching for any signs of complications. Given their small size and specific breed needs, Shih Tzus may require extra attention during recovery.

10. The Role of Diet and Exercise Post-Spaying

After spaying, a Shih Tzu’s diet and exercise regimen should be carefully monitored to prevent obesity, a common issue in the breed. Collaborate with your vet to adjust her diet and exercise regime to support a healthy weight and lifestyle.


Determining the best age to spay your female Shih Tzu involves careful consideration of the breed’s unique characteristics and health concerns. Consult with your veterinarian, weigh the benefits and risks of spaying at different ages, and consider alternative methods if they align better with your dog’s health needs. Whichever option you choose, the priority should always be the health and happiness of your beloved Shih Tzu.


Frequently Asked Questions A Shih Tzu Owner Might Ask Before Having Their Shih Tzu Spayed

1. What is the best age to spay my Shih Tzu?

The recommended age to spay a Shih Tzu is typically between 6 to 9 months, ideally before her first heat cycle. This timing helps reduce the risk of mammary tumors and reproductive health issues. However, each dog is unique, so it’s important to consult with your veterinarian for personalized advice based on your Shih Tzu’s health and lifestyle.

2. Will spaying change my Shih Tzu’s personality?

Spaying your Shih Tzu is unlikely to change her fundamental personality. It can reduce behaviors linked to the reproductive cycle, such as moodiness during heat cycles. Overall, your Shih Tzu will remain the same affectionate and lively pet, with some potential behavioral benefits.

3. Are there long-term health benefits to spaying my Shih Tzu?

Yes, spaying offers significant long-term health benefits for Shih Tzus. These include a reduced risk of mammary tumors, ovarian and uterine cancers, and the prevention of pyometra, a serious uterine infection. Spaying also eliminates the risks associated with pregnancy and birthing.

4. What are the risks associated with spaying my Shih Tzu?

Spaying is a surgical procedure and carries standard risks such as bleeding, infection, and anesthesia reactions. For Shih Tzus, there’s a slight risk of urinary incontinence and obesity post-spaying. Discuss these risks with your vet to make an informed decision.

5. How long is the recovery period after spaying a Shih Tzu?

The recovery period for a Shih Tzu after spaying typically lasts about 10 to 14 days. During this time, limit her physical activity, monitor the incision site for signs of infection, and follow your vet’s post-operative care instructions closely.

6. Is spaying a painful procedure for Shih Tzus?

Spaying is a surgical procedure that can cause some discomfort. However, veterinarians use anesthesia during the surgery and provide pain management afterward to ensure your Shih Tzu is comfortable. Most Shih Tzus recover quickly with proper care and pain management.

7. Will my Shih Tzu gain weight after being spayed?

Spaying can lead to metabolic changes that might result in weight gain if not managed properly. It’s important to monitor your Shih Tzu’s diet and exercise regimen post-surgery. Your vet can recommend dietary adjustments and an appropriate exercise routine to maintain a healthy weight.

8. What are the alternatives to traditional spaying for Shih Tzus?

Alternatives to traditional spaying include ovary-sparing spay (OSS) and laparoscopic spay. OSS leaves the ovaries intact while removing the uterus, and laparoscopic spay is a less invasive method. These alternatives may be suitable for some Shih Tzus, depending on individual health considerations.

9. Can I spay my Shih Tzu during her heat cycle?

While it’s technically possible to spay a Shih Tzu during her heat cycle, it’s generally not recommended. Surgery during heat can be more complex due to increased blood flow to the reproductive organs, leading to a higher risk of complications. It’s best to plan the spaying before or after a heat cycle.

10. How should I care for my Shih Tzu after she’s spayed?

After spaying, ensure your Shih Tzu has a quiet place to rest and recover. Keep her from excessive activity, regularly check the incision site, and prevent her from licking or biting it. Follow your vet’s instructions regarding diet, medication, and follow-up visits for a smooth recovery.
