Finding the best dog food for shih tzu isn’t about picking one brand above all others. It’s about matching your dog’s specific needs to the right recipe. You must consider your Shih Tzu’s age, their activity level, and any known digestive sensitivities. Some dogs need help with their coat, while others need a higher protein intake for their daily energy. Choosing between Royal Canin Shih Tzu and Purina Pro Plan Small often comes down to whether you prioritize breed-specific kibble design or a texture-rich shredded blend.
1. ROYAL CANIN Shih Tzu Adult Dry Dog Food
Best for: Owners of purebred adults who want breed-specific nutrition and care.
This food is designed specifically for the Shih Tzu breed aged 10 months and older. The kibble has a unique shape that makes it easier for a dog with a short muzzle and underbite to pick up and chew. It also includes an exclusive mix of EPA, DHA, and vitamin A to help support the skin and coat.
The formula focuses on highly digestible proteins and precise fiber content. This helps manage the quality and odor of your dog’s stool, which is a common concern for small breed owners. It’s a specialized choice that leaves little room for guesswork regarding breed-specific requirements.
You should choose this formula if you prioritize specific nutrients like biotin and omega fatty acids for coat maintenance. The decision rule is simple: if your dog is a purebred adult, this kibble supports their specific anatomy. If your dog is under 10 months, you must avoid this adult-specific formula to ensure they receive the correct growth nutrients.
Good if:
- Your dog is a purebred adult.
- You want kibble shaped for a short muzzle.
- You prioritize coat health and digestion.
Skip it if:
- Your dog is under 10 months old.
- You prefer a mixture of textures rather than a single kibble type.
2. Purina Pro Plan Small Breed Dry Dog Food
Best for: Highly active small dogs that need extra protein and variety.
This blend features a mix of bite-sized kibble and tender, shredded pieces. This texture is designed to be more appealing to picky eaters who might get bored with standard dry food. It uses real chicken as the first ingredient to provide high-quality protein for lean muscle mass.
The formula is also fortified with guaranteed live probiotics. These are included to support your dog’s digestive health and immune system, which is vital for smaller dogs with fast metabolisms. It provides a high-protein profile for those who spend their day running and playing.
If your dog is sedentary, skip this formula. The high-protein content is specifically engineered to meet the energy demands of highly active breeds. Feeding this to a dog with low activity levels may lead to unnecessary weight gain.
Good if:
- Your Shih Tzu is very active.
- Your dog prefers different textures in their bowl.
- You want probiotic support for digestion.
Skip it if:
- Your dog has a very simple palate and prefers uniform kibble.
- Your dog is sedentary and doesn’t need a high-protein formula.
- You’re looking for the old SAVOR branding, as this is the same product under a new name.
3. Hill’s Science Diet Adult 1-6 Small & Mini Dry Dog
Best for: Dogs that require easy-to-digest ingredients and balanced nutrition.
Hill’s focuses on lean muscle support using high-quality protein. The balance of fats, carbs, and protein is intended to maintain an ideal body weight. The formula includes pumpkin to aid healthy digestion.
This brand is the number one choice for US veterinarians. The ingredients are natural, providing a straightforward approach to daily nutrition.
Good if:
- You want a veterinarian-recommended formula.
- Your dog has a sensitive stomach.
- You’re focused on weight management.
Skip it if:
- You want a formula with specific breed-tailored kibble shapes.
- Your dog requires extremely high protein levels.
4. Blue Buffalo Life Protection Formula Chicken Small Breed Dry Dog
Best for: Owners looking for a natural formula with antioxidant support.
This formula starts with real chicken and includes wholesome grains like brown rice and barley. It features “LifeSource Bits,” which are a blend of antioxidants, vitamins, and minerals. These bits are formed at a lower temperature to help keep their potency high.
The food is free from poultry by-product meals, corn, wheat, and soy. It also includes natural prebiotic fiber to support stool quality and digestion. This is a comprehensive natural option for those who want to avoid artificial flavors or preservatives.
The recipe is specifically designed by veterinarians and animal nutritionists to support lean muscle growth. It also contains Omega 3 and 6 fatty acids to ensure healthy skin and a shiny coat.
Good if:
- You prefer a natural ingredient list.
- You want antioxidant support for the immune system.
- You need to avoid corn, wheat, or soy.
- You want steady energy for an active small dog.
Skip it if:
- Your dog is allergic to specific grains like barley or rice.
- You want a grain-free option.
- You require a formula that excludes all grains, as this recipe relies on oatmeal and brown rice for digestion.
5. Blue Buffalo Wilderness Chicken Small Breed Adult Dry Dog Food
Best for: Very active Shih Tzus that thrive on higher protein levels.
It uses real chicken as the first ingredient and includes peas and sweet potatoes for digestive support. The kibble is small to suit smaller jaws and encourages tartar removal through chewing.
Like other Blue Buffalo products, it includes the LifeSource Bits for immune support. These are formed at a lower temperature to ensure optimal potency for your pet. It’s designed to provide steady energy through complex carbohydrates like oats, barley, and brown rice. This food is a good fit for dogs that need more protein to sustain their daily activity levels.
Good if:
- Your dog is very energetic.
- You want a grain-inclusive but high-protein diet.
- You want kibble that encourages chewing.
Skip it if:
- Your dog is less active and prone to weight gain.
- You prefer a lower-protein, more moderate diet.
- You’re looking for a grain-free option, as this formula includes oats, barley, and brown rice.
The brand adheres to the True Blue Promise, meaning there are no poultry by-product meals, corn, wheat, soy, artificial flavors, or preservatives in the bag.
Where These Overlap
Most of these foods overlap in their commitment to small-breed health. Nearly all the options here, such as Blue Buffalo Life Protection and Hill’s Science Diet Small, emphasize digestive support through prebiotics or fiber.
If you’re choosing between the two Blue Buffalo options, the main difference is the protein density. The Wilderness line is for the high-energy dog, while the Life Protection line is for the standard, balanced adult.
Royal Canin stands apart due to its breed-specific kibble shape, which none of the other brands offer. This unique design is specifically intended for the short muzzle and underbite of a purebred Shih Tzu.
For those needing standard nutrition, Purina Pro Plan Small and Hill’s Science Diet Small are very close in their functional goals. Both focus on lean muscle support and high-quality protein. If your priority is immune health, look for options like Purina Pro Plan, which includes guaranteed live probiotics, or Blue Buffalo’s antioxidant-rich LifeSource Bits.
Still Not Sure?
How often will I really use it?
If your dog is a daily eater who enjoys a consistent routine, you should choose a formula that’s easy to source and reliable, like Hill’s Science Diet Small. If your dog is a grazing feeder or very picky, the textured pieces in Purina Pro Plan Small might keep them interested.
What do I already own that this has to work with?
If you already use supplements for skin or coat, you may not need the specific additives in Royal Canin Shih Tzu. However, if you’re looking for an all-in-one solution that covers skin, coat, and digestion without extra pills, Royal Canin Shih Tzu is the most complete choice.
What am I most likely to regret choosing?
You’re most likely to regret picking a high-protein formula, like Blue Buffalo Wilderness Small, if your dog is older or has a low activity level. Excess protein and calories can lead to weight issues in less active Shih Tzus, so be honest about your dog’s daily exercise levels before choosing.

Frequently Asked Questions
What does it mean if my dog refuses the food?
If your dog refuses the food, it may be a texture preference. Small dogs can be picky about kibble size. The Association of American Feed Control Officials provides guidelines on nutritional profiles, but they don’t account for individual taste. If they refuse it, try mixing in a small amount of warm water.
Do I need to rotate between different brands?
You don’t need to rotate between brands if your dog is doing well on one. Sudden changes can upset a small dog’s stomach. If you decide to switch, do it gradually over a week by mixing the new food with the old, slowly increasing the new portion.
Can I feed this to my puppy?
No, you shouldn’t feed adult formulas to a puppy. Shih Tzu puppies have different growth requirements than adults. You must look for a label that specifically states it’s for “growth” or “puppies” to ensure they get the correct balance of calcium and phosphorus for their developing bones.
Is the kibble size really important?
Yes, kibble size is important for the Shih Tzu. Formulas like Royal Canin Shih Tzu are specifically engineered to make the eating process easier and more comfortable for their unique facial structure.
Conclusion
If your dog is a purebred adult, Royal Canin Shih Tzu is the best starting point for its specialized design. For active dogs that need more energy and interest at mealtime, Purina Pro Plan Small is a great option. Speak with your veterinarian to confirm which nutritional profile best suits your dog’s health history.
