  • Faster metabolism than larger breeds
  • Higher risk of dental issues
  • Tendency toward weight gain
  • Sensitive digestive system

Shih Tzus require carefully balanced diets tailored to their weight, activity levels, and life stage to stay healthy and prevent obesity. Their daily caloric intake ranges from 200 to 450 calories, with portion sizes varying based on weight and activity level.

Essential nutrients like protein (18-25%), fat (12-15%), and carbohydrates (30-40%) support their energy needs, while fiber (3-5%) aids digestion. Key vitamins and minerals—such as Vitamin A for coat health, calcium for strong bones, omega-3 fatty acids for skin and coat, and glucosamine for joint health—ensure overall well-being.

Always consult a veterinarian or refer to AAFCO standards to create the perfect meal plan for your Shih Tzu.

For joint health, supplements like Nutramax Dasuquin with MSM and Cosequin Maximum Strength offer beneficial levels of glucosamine, chondroitin, and MSM to support cartilage health, reduce stiffness, and enhance mobility. However, selecting the right product tailored to your Shih Tzu’s specific needs is crucial. Consulting your veterinarian is essential, as the variety of products available is designed to address different conditions. Using the wrong supplement can potentially do more harm than good, making professional guidance vital for your pet’s safety and well-being.

For skin and coat health, Zesty Paws Omega Bites combine omega-3 fatty acids with biotin and Vitamin E to promote a shiny coat and reduce itching, while Nordic Naturals Omega-3 Pet offers high-quality EPA and DHA for coat maintenance and heart health.

Digestive support supplements such as Purina FortiFlora, delivering billions of CFUs of beneficial probiotics, and Nummy Tum Tum Pure Pumpkin, rich in natural fiber, help improve stool quality and regulate digestion. But if there is an underlying condition, these suppliments might not be the answer and then you will know it is time to see the vet for further investigation.

When introducing supplements, monitor your Shih Tzu for visible improvements like smoother movement, reduced scratching, or better stool consistency, and stay alert for any adverse reactions such as vomiting or loose stool.

Always consult your veterinarian before starting a new supplement, as over-supplementation or inappropriate use can cause harm. Choosing tested and trusted products ensures your Shih Tzu receives safe and effective support without unnecessary risks. Regular veterinary check-ups will help fine-tune their dietary regimen and maintain their overall health.

Weight Management & Obesity Prevention

Body Condition Score (BCS) Check

We understand that maintaining a healthy weight for your Shih Tzu can feel challenging at times, but it’s one of the most effective ways to ensure a long, active, and happy life. Like many Shih Tzu owners, you might wonder if your furry companion is at their ideal weight. This is where tools like the Hill’s Body Fat Index (BFI) and the Body Condition Score (BCS) come in handy.

How These Tools Work Together:
The Hill’s BFI provides precise measurements of body fat percentage, offering a scientific foundation for weight management plans. On the other hand, the BCS system uses visual and tactile assessments to evaluate your Shih Tzu’s physique. Together, these methods create a comprehensive picture of your pet’s health.

Mapping the Two Systems:

  • BCS 1–3/9: Underweight (BFI < 15%)
    Visible ribs, spine, and hip bones with severe abdominal tuck.
  • BCS 4–5/9: Ideal Weight (BFI 15–25%)
    Ribs are palpable but not visible, with a defined waist and abdominal tuck.
  • BCS 6–9/9: Overweight to Obese (BFI > 25%)
    Ribs are difficult to feel, with no visible waist and fat deposits noticeable.

By regularly assessing your Shih Tzu using these methods, you can monitor weight changes effectively and adjust their diet and exercise routines as needed. If you’re ever unsure, we recommend consulting your veterinarian for personalized advice.

🏃 Discover how much exercise your Shih Tzu needs and the best activities to keep them fit in our Shih Tzu Exercise Requirements Guide.

Prevention Strategies for Pet Health

Measure Every Meal

Special Dietary Considerations

Common Food Sensitivities
  • 1 Wheat and grains: Can trigger digestive upset or allergies
  • 2 Dairy products: Many dogs are lactose intolerant leading to diarrhea
  • 3 Artificial preservatives: Can cause allergic reactions
  • 4 Certain proteins: Sensitivities to chicken or beef
Joint Issues
  • 1 Glucosamine supplements: Maintain cartilage health, reduces discomfort
  • 2 Omega-3 fatty acids: Reduce inflammation
  • 3 Anti-inflammatory ingredients: Natural support
Skin Allergies
  • 1 Limited ingredient diets: Help identify allergens
  • 2 Novel protein sources: Less likely to trigger allergies like venison or duck
  • 3 Added omega fatty acids: Promote healthy shiny coats, reduces irritation or flakiness
Dental Health
  • 1 Appropriate kibble size: Helps clean teeth
  • 2 Dental-specific treats: Reduce tartar buildup and freshen breath
  • 3 Avoid sticky foods: Prevent plaque buildup and decay

Addressing your Shih Tzu’s special dietary needs ensures their comfort and health. Food sensitivities to grains, dairy, or certain proteins like chicken can be managed with elimination diets or novel protein options like duck. 💡 Struggling with tear stains? Check out our Shih Tzu Tear Stains: Complete Prevention & Treatment Guide for tips to keep your pup’s face clean and healthy.

Joint issues benefit from glucosamine and omega-3s to reduce discomfort and inflammation, while omega fatty acids support healthy skin and coats, minimizing irritation.

For dental health, choose kibble designed to clean teeth and dental-specific treats to reduce tartar.

Always consult a veterinarian for tailored advice and to safely implement dietary changes, ensuring these needs are effectively managed.

Common Diet Mistakes to Avoid

Overfeeding
  • Using wrong portion sizes
  • Too many treats
  • Table scraps
Poor Food Transitions
  • Sudden changes
  • Mixed feeding methods
  • Inconsistent schedules
Inappropriate Treats
  • Human food rewards
  • High-calorie dog treats
  • Frequent treating

Avoiding common diet mistakes is vital for your Shih Tzu’s health. Overfeeding, giving excessive treats, or feeding table scraps can lead to obesity and long-term health issues like diabetes or pancreatitis.

Sudden food changes or inconsistent schedules may cause digestive upset, while high-calorie or human treats undermine proper nutrition. Use measuring cups for portions, choose low-calorie dog treats, and transition foods gradually to maintain a balanced diet and support your Shih Tzu’s overall well-being.

Expert Q&A: Shih Tzu Diet & Nutrition

Dr. Esther Knoetze (BSc)(BVSc), answers your questions about Shih Tzu nutrition and diet management.

Mealtime Challenges

How can I stop my Shih Tzu from begging?

Start with our proven 3-step method:

  • Feed at consistent times daily
  • Remove food after 20 minutes
  • Never feed from the table

Consistency is key – begging is a learned behavior that can be modified with proper training. Pair consistent feeding routines with positive reinforcement, like praising or rewarding calm behavior, to reinforce desirable habits and discourage begging over time.

My Shih Tzu is a picky eater. Should I be worried?

First, let’s rule out dental issues – many ‘picky’ dogs actually have sensitive teeth. Try these proven solutions:

  • Serve food at room temperature
  • Maintain strict meal times
  • Remove uneaten food after 20 minutes
  • Avoid frequent food changes

Remember: While occasional picky eating is common, prolonged refusal to eat may signal dental pain, digestive issues, or other health problems. Consult your veterinarian if the behavior persists or worsens.

My Shih Tzu eats too fast. What can I do?

Fast eating can lead to digestive issues, choking or, in rare cases, bloating. Supervise meals, and consider slow-feeder bowls or puzzle toys to encourage slower, safer eating. Here are effective solutions:

  • Use slow-feeder bowls
  • Try food puzzle toys
  • Implement scatter feeding
  • Split into multiple small meals

Weight Management

How fast should my overweight Shih Tzu lose weight?

Aim for a loss of 1-2% of body weight per week:

  • 16lb dog: target 0.16-0.32lb weekly loss
  • Track progress with weekly weigh-ins
  • Adjust portions monthly
  • Include appropriate exercise

Work with your veterinarian to monitor progress through regular weigh-ins and ensure the weight loss is healthy. Sudden or drastic weight loss can be harmful and should be avoided.

Can I exercise my senior Shih Tzu to help with weight loss?

Yes, but start gently:

  • 10-15 minute walks twice daily
  • Swimming (with proper support)
  • Indoor obstacle courses
  • Mental stimulation activities

Start with low-impact activities like short walks or swimming, gradually increasing as tolerated. Incorporate joint-friendly supplements like glucosamine to support mobility and reduce discomfort.

Special Dietary Needs

What treats are safe for my diabetic Shih Tzu?

Focus on low-glycemic options:

  • Fresh green beans
  • Small pieces of lean meat
  • Sugar-free jerky (watch sodium)
  • Freeze-dried liver (in moderation)

Stick to treats like green beans or lean meat in small portions to avoid blood sugar spikes. Always verify treat options with your veterinarian.

How can I prevent my Shih Tzu from stealing other dogs’ food?

This requires management:

  • Feed in separate rooms
  • Use raised bowls for larger dogs
  • Consider microchip-activated bowls
  • Supervise all mealtimes

Along with separate feeding spaces, train your Shih Tzu to respect boundaries using simple commands like “leave it” or “stay.”

Seasonal Adjustments

Should I change my Shih Tzu’s diet in summer?

Make these seasonal adjustments:

  • Increase water content in food
  • Feed smaller, more frequent meals
  • Adjust portions based on activity
  • Consider frozen treats for enrichment

Ensure your Shih Tzu has access to fresh water throughout the day, as their flat faces make them more prone to overheating. Signs of dehydration include dry gums, sunken eyes, and lethargy.

What’s the best diet for my show Shih Tzu’s coat?

Age & Health Transitions

When should I switch my Shih Tzu to senior food?

Look for these signs around age 7-8:

  • Slowing metabolism
  • Less activity
  • Joint stiffness
  • Dental changes

Consider these dietary adjustments:

  • Lower calorie density (about 350-375 kcal/cup)
  • Higher fiber content for digestion
  • Added glucosamine for joint health
  • Easier-to-digest protein sources

Remember, age alone isn’t the deciding factor – consider overall health and activity level. Always consult with your vet before making the switch.Gradually transition to senior food over 10-14 days to reduce the risk of digestive upset. Always consult your veterinarian to ensure the new food meets their specific health needs.

How do I safely transition to a new food?

Follow this 7-day transition plan:

  • Days 1-2: 75% old food, 25% new food
  • Days 3-4: 50% old food, 50% new food
  • Days 5-6: 25% old food, 75% new food
  • Day 7: 100% new food

Watch for any digestive issues during the transition. For dogs with sensitive stomachs, extend the transition to 10-14 days, gradually increasing the proportion of new food. Monitor for signs of digestive upset like diarrhea or vomiting.

Should I adjust my Shih Tzu’s diet in winter?

Consider these winter adjustments:

  • Slightly increased calories if outdoor activity continues
  • Warm meals are acceptable
  • Adjust portions based on indoor activity levels
  • Maintain adequate hydration despite cooler weather
