Top 5 Best Dog Foods for Shih Tzus with Allergies

1- Royal Canin Shih Tzu Adult Dry Food: The Ultimate Hypoallergenic Choice for Sensitive Shih Tzus

When it comes to managing food allergies in Shih Tzus, Royal Canin Shih Tzu Adult Dry Food stands out as a top-tier, breed-specific solution. Designed by veterinary nutritionists, this formula addresses the unique needs of Shih Tzus with mild to moderate food sensitivities, combining hydrolyzed soy protein for reduced allergenicity with targeted nutrients for optimal health.

Why It’s Great for Allergies

Royal Canin’s breed-specific formulation is a game-changer for Shih Tzus prone to allergic reactions. The hydrolyzed soy protein undergoes a specialized process that breaks down proteins into smaller molecules, significantly lowering the risk of triggering immune responses. This makes it an excellent choice for dogs with poultry, beef, or dairy sensitivities, common culprits behind itching, ear infections, and digestive upset in the breed.

Key Features for Allergy-Prone Shih Tzus

1. Omega-3 Fatty Acids (EPA & DHA): Essential for maintaining skin barrier health and reducing inflammation caused by allergic dermatitis.

2. Optimal Kibble Size & Shape: Designed for brachycephalic (flat-faced) breeds, the L-shaped kibble encourages slower chewing, aiding digestion and minimizing gulping—a common issue in Shih Tzus.

3. Prebiotics + Digestive Enzymes: Supports gut health, crucial for dogs with food intolerances, by promoting a balanced microbiome.

4. Biotin & Zinc: Strengthens skin and coat, addressing the excessive scratching and hot spots linked to allergies.

Best For: Shih Tzus with Mild to Moderate Food Sensitivities

This formula is ideal for Shih Tzus showing:

• Itchy skin or recurrent ear infections (common signs of protein allergies)

• Loose stools or occasional vomiting after meals

• Dull coat or flaky skin due to nutrient deficiencies

Pro Tip: Transition gradually over 7–10 days to avoid digestive upset, and pair with Royal Canin’s Shih Tzu Wet Food for added hydration and palatability.

Real Results: Many owners report noticeable improvements in itching and coat quality within 4–6 weeks, with fewer ear infections long-term.

Note: For severe allergies, consult your vet about pairing this with an elimination diet to pinpoint triggers.

 

2-Hill’s Science Diet Sensitive Stomach & Skin: The Perfect Solution for Shih Tzus with Digestive and Skin Allergies

For Shih Tzus struggling with both stomach sensitivities and skin allergies, Hill’s Science Diet Sensitive Stomach & Skin offers a scientifically formulated solution that targets dual symptoms effectively. This vet-recommended dry food combines prebiotic fiber for gut health and vitamin E for skin support, making it ideal for dogs prone to food-related reactions.

Why It’s Great for Shih Tzus with Allergies

Hill’s Science Diet is specially crafted to address digestive upsets and skin irritations—two common issues in Shih Tzus with food sensitivities. The prebiotic fiber (from beet pulp and chicory) nourishes beneficial gut bacteria, improving digestion and stool quality, while vitamin E and omega-6 fatty acids promote a healthy skin barrier, reducing itching and flakiness.

Key Features for Sensitive Shih Tzus

1. Prebiotic Fiber: Supports balanced digestion, reducing episodes of diarrhea and vomiting.

2. Vitamin E & Omega-6 Fatty Acids: Enhances skin hydration and coat shine, minimizing allergic dermatitis.

3. No Artificial Colors, Flavors, or Preservatives: Eliminates unnecessary additives that may trigger reactions.

4. Clinically Proven Antioxidant Blend: Strengthens the immune system, helping Shih Tzus combat inflammation from allergies.

5. Highly Digestible Ingredients: Gentle on sensitive stomachs while ensuring nutrient absorption.

Best For: Shih Tzus with Both Skin + Stomach Issues

This formula is perfect for Shih Tzus experiencing:

• Frequent itching, redness, or hot spots (skin allergies)

• Loose stools, gas, or occasional vomiting (digestive sensitivities)

• Dull coat and dry skin due to poor nutrient absorption

Pro Tip: For best results, pair this food with Hill’s Science Diet Sensitive Stomach & Skin Wet Food to increase moisture intake—especially beneficial for Shih Tzus prone to dehydration.

Real Results: Many owners report improved digestion within 10 days and healthier skin within 4–6 weeks of switching.

Note: If symptoms persist, consult your vet to rule out environmental allergens (like pollen or dust mites) alongside food triggers.

3-Purina Pro Plan Sensitive Skin Salmon & Rice: Ideal for Shih Tzus with Protein Allergies

For Shih Tzus suffering from poultry or beef allergies, Purina Pro Plan Sensitive Skin Salmon & Rice offers an excellent novel protein solution. This formula features salmon as the primary protein source, significantly reducing the risk of allergic reactions while delivering high levels of EPA/DHA omega-3 fatty acids for optimal skin and coat health.

Why It’s Great for Allergic Shih Tzus

The single animal protein (salmon) minimizes exposure to common allergens, while live probiotics support digestive health—a crucial factor for dogs with food sensitivities. The grain-inclusive recipe with rice provides easily digestible carbohydrates, making it gentle on sensitive stomachs.
