A Shih Tzu puppy is a tiny, flat-faced eater with a finicky stomach, and picking the wrong kibble means loose stool, picky mealtimes, and a coat that loses its shine. The real answer is a small-breed puppy formula with tiny kibble they can actually pick up and digest easily, which is exactly what this guide sorts through. You will get nine specific recipes, the honest trade-offs of each, and a clear verdict on which one belongs in your puppy’s bowl.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Feeding a flat-faced puppy the right kibble size and nutrition matters, so here is the honest breakdown of the best dog food for shih tzu puppy.
Our Picks at a Glance
How To Choose The Best Dog Food for Shih Tzu Puppy
Your Shih Tzu puppy has a brachycephalic (flat) face and a tiny jaw, which physically makes eating harder than it is for a longer-nosed dog. The right food solves two problems at once: the kibble must be small enough to grab, and the recipe must be gentle enough to avoid the loose stools that plague this breed.
Kibble Size and Shape
Standard adult kibble is simply too large for a Shih Tzu puppy’s mouth, causing them to gulp air or skip meals entirely. A small-breed formula with tiny kibble lets your puppy chew comfortably, which is the first thing owners of flat-faced dogs notice when they switch.
Digestive Support and Stool Quality
Shih Tzus are notorious for sensitive stomachs, so look for recipes with prebiotics or probiotics, which are fibers and beneficial bacteria that help food break down smoothly. A food that causes loose stool is a losing trade, no matter how premium the protein source is.

In-Depth Reviews
1. Hill’s Science Diet Puppy Small Bites Dry Dog Food
Our pick — over 4.5★ from 6,500+ verified ratings; the strongest balance of quality and price.
The vet-backed staple with tiny bites that toy breeds happily crunch.
When you want the reassurance of a brand that vets recommend most, this is the one, with balanced minerals for growing bones and teeth and DHA plus Fish Oil for healthy brain and eye development. The kibble is genuinely small, and owners mention that “small kibble is nice for toy breed puppies,” making it an easy chew for a young Shih Tzu.
High-quality proteins fuel muscle growth, while antioxidants and natural ingredients support the immune system. Owners return for repeat purchases, praising the firm stools their puppies produce.
The recurring praise centers on how readily puppies eat it, with the chicken and brown rice flavor winning over even cautious eaters. It holds a top rating across a huge number of owner reviews.
Trusted formula: A balanced, natural-ingredient puppy diet from the vet-recommended brand, backed by a massive base of happy owners.
Fair trade-off: Digestibility feedback is a mixed bag for some puppies, so transition slowly over the first week.
2. ROYAL CANIN Shih Tzu Puppy Dry Dog Food
The only recipe engineered around a Shih Tzu’s flat muzzle and underbite.
This is the pick that takes the guesswork out of feeding, because Royal Canin designed the kibble shape specifically for a Shih Tzu’s short muzzle and underbite, not just for small breeds in general. It is formulated for purebred Shih Tzus from 8 weeks to 10 months old, so the nutrition targets the exact growth window your puppy is in right now.
Buyers report firmer stools within days of switching to this breed-specific formula. High-quality proteins and prebiotics reduce stool volume and odor, a relief for small-space living.
Nutrients like vitamin E and omega fatty acids support the breed’s long coat and developing immune system. It holds a top-tier rating across thousands of owner reviews.
What wins owners over
- Unique kibble shape fits a Shih Tzu’s short muzzle perfectly
- Owners see firmer stools and better digestion quickly
- Targeted nutrients for the breed’s long, growing coat
Reality check
- The 2.5 lb bag is small, so you will reorder often
- Some owners feel the value is a split decision for the portion size
Built for this breed: This is your pick if you want a formula that matches your Shih Tzu’s exact anatomy and growth stage.
Think twice if: You want a bigger bag to last longer, since this one comes in at just 2.5 pounds.
3. Wellness CORE Small Breed Puppy Dry Dog Food
A protein-packed, grain-free recipe for puppies that need to feel full.
This grain-free formula is built on 53% high-quality protein ingredients from responsibly sourced turkey, aimed at supporting leaner body mass and muscle tone. A 25-year Dachshund owner who researched extensively chose this and reported a puppy that thrives with well-formed stools, healthy growth, a shiny coat, and good breath.
The recipe is free of corn, wheat, soy, by-products, and artificial additives, with DHA for brain development and calcium and phosphorus for bones. Owners note the bag includes a ziplock closure to keep the fresh kibble sealed between servings.
What wins people over is the taste, with puppies consistently preferring it over their old food. Just know that digestibility gets mixed feedback, so a brief adjustment period is normal for sensitive tummies.
Why it stands out
- Grain-free with 53% high-quality protein ingredients
- Ziplock packaging keeps kibble fresh
- Owners see shiny coats and good breath
Know before you buy
- Some customers note digestion issues during the switch
- High-protein recipes can be too rich for very sensitive puppies
Reach for this if: You want a grain-free, high-protein diet that keeps a growing puppy satisfied between meals.
Look elsewhere if: Your puppy has a history of stomach upset, since the digestibility reaction here is genuinely split.
4. Bil-Jac Small Breed Puppy Dry Dog Food
Soft, porous bites that make the leap from milk to solid food painless.
The proprietary shape here is soft and porous, which makes it genuinely easy for tiny puppy teeth to pick up and chew, a huge plus when your Shih Tzu is still learning to eat solid food. The recipe uses 5 lbs of fresh, real chicken in every 6 lb bag to supply the amino acids needed for lean muscle and strong organs.
Oatmeal and yams act as gentle, high-quality fiber sources to soothe sensitive puppy stomachs and support maximum nutrient absorption. The taste is the thing owners rave about, with picky eaters who walk away from homemade food finally committing to a bowl of this.
The actual bag weight comparison matters here too: this comes in at 6 pounds, giving you more food per bag than the 4-pound Wellness CORE option above.
Easy transition: The soft, chewable bites are ideal for puppies moving off weaning foods.
Honest caveat: Stool odor can be strong for some pups, and the recipe’s appeal may make your puppy act hungrier than the portion guide suggests.
5. Merrick Lil’ Plates Premium Grain Free Dry Puppy Food
Real deboned chicken first, with glucosamine for growing hips and joints.
Real deboned chicken leads the ingredient list in this grain-free recipe, delivering the protein a toy breed needs for strong muscles and steady energy. Where this one stands apart is the addition of high levels of glucosamine and chondroitin to support healthy hips and joints, plus omega-6 and omega-3 fatty acids to nourish skin and that signature Shih Tzu coat.
The wholesome, smaller-sized kibble is tailored for small dog breeds and works to clean teeth and freshen breath as your puppy chews. Probiotics are added to support digestive health, and a holistic blend of high protein and healthy fats helps maintain energy levels.
Puppies gobble it down, with owners of 4-month-old pups reporting an instant switch from a breeder-recommended food they refused. The main hesitation from owners is the cost per pound, which runs higher than some larger bags on the market.
The highlights
- Deboned chicken is the first ingredient
- Glucosamine and chondroitin for joint health
- Kibble helps clean teeth while chewing
Consider this
- More expensive per pound than many alternatives
- Some picky eaters refuse it even when others love it
Best if: You want a grain-free recipe with extra joint support and coat-nourishing fatty acids.
Watch out for: The higher price per pound if you are feeding a puppy with a big appetite.
6. Now Fresh Grain-Free Small Breed Dry Puppy Food
A chicken-free, multi-protein blend that lists your Shih Tzu by name.
This recipe is explicitly tailored for small and toy breeds, with the maker naming Shih Tzus directly alongside Frenchies, Chihuahuas, Yorkies, and Pugs, and the tiny kibble size backs that up. It is chicken-free, leading instead with fresh de-boned turkey, salmon, and duck to provide a highly digestible multi-protein blend for healthy muscle development.
Digestive health gets a real focus here, with fiber-rich sweet potato and pumpkin for sensitive stomachs, fortified with probiotics for healthy digestion and stool quality. The recipe is also free of by-products, meat meals, artificial flavors, colors, and preservatives.
Owners of a 7-month-old Maltese note that their pup eats it regularly every day, and a Miniature Schnauzer owner specifically praises the lack of fillers like corn and wheat. One Shih Tzu mix owner simply calls it “good for my pomshitzu,” confirming the breed fit.
Built for toy breeds: A chicken-free, multi-protein recipe with tiny kibble and probiotics, purpose-made for flat-faced small dogs.
Notable point: The 3.5-pound bag is the smallest of the dry options here, so plan for frequent reorders.
7. ORIJEN Grain Free WholePrey Small Breed Puppy Recipe
A prey-model diet with a square kibble sized at 6-7 mm for small jaws.
This grain-free recipe follows a WholePrey philosophy, meaning it includes nourishing poultry, fish, and organs to mimic what a puppy’s ancestors consumed in the wild. The square kibble has a diameter of 6-7 mm and a width of 5-6 mm, a precise size that owners confirm is perfect for small dogs and great for training treats.
EPA and DHA from salmon, whiting, haddock, and pollock oil support your small breed puppy’s developing brain, while fiber plus a blend of pre- and probiotics support digestive health. Protein and minerals from animal ingredients help growing bones and healthy muscle development.
Owners with sensitive-stomached dogs report it causes no tummy problems, with one pug owner using it as a break from prescription food. The honest trade-offs are a strong odor that some owners notice and a value-for-money debate, as this sits at a premium price point.
The strengths
- WholePrey formula with organs for a natural diet
- Precise 6-7 mm kibble size for small jaws
- EPA and DHA from fish oil for brain development
Keep in mind
- The food has a noticeably strong odor
- Premium pricing makes the value a split decision
Choose this for: A biologically appropriate, high-protein diet with a precisely sized kibble for toy breeds.
Be ready for: The strong smell and the premium cost per bag.
8. NutriSource Chicken & Rice Premium Wet Puppy Food
A moisture-rich pate with a proprietary gut health system inside.
If your Shih Tzu puppy needs extra hydration or you want to add moisture and aroma to dry kibble, this wet pate is the tool, with a moisture-rich texture that puppies love at first bite. The GOOD4LIFE Gut Health System brings probiotics, prebiotics, and trace minerals to nourish the gut microbiome and support healthy digestion.
Real chicken delivers a rich, wholesome taste with no corn, wheat, soy, or by-products, and the recipe is complete and balanced for growth per AAFCO standards. It works as a full meal or a topper, and the maker suggests rotating it with any NutriSource dry recipe for variety.
The main frustration here is shipping, with some owners receiving crushed cans in the case, a handling issue rather than a recipe flaw. The 12-pack gives you a solid stock, and the family-owned Minnesota maker has been at it since 1964.
Hydration helper: A complete wet meal or kibble topper that adds moisture and gut-supporting probiotics.
Shipping caveat: Some cases arrive with dented cans, so inspect your delivery promptly.
9. Purina Pro Plan Small Breed Wet Puppy Food
A 24-can stash that turns kibble-shy puppies into enthusiastic eaters.
This wet food is specially formulated for puppies up to 1 year old, with DHA for brain and vision development and chicken as the first ingredient for high-quality protein to build lean muscles. As a small breed formula with chicken and brown rice, it supports a healthy immune system and nourishes healthy skin and coat.
Owners of a 10-week-old puppy mix a small amount of this soft food with their small breed kibble, coating each piece for flavor, and report their baby eats it right up. The 24-can pack provides complete and balanced nutrition with no artificial colors, flavors, or preservatives, made at Purina-owned U.S. facilities.
The value is a strong point, with owners calling the price good for the quantity, though palatability does get mixed feedback across different pups. The rare complaint is a damaged box in shipping, not the food itself.
Why it works
- Huge 24-can pack for a long-lasting supply
- Chicken is the first ingredient
- Great for mixing with kibble to boost flavor
The downsides
- Not every puppy loves the taste
- Some shipments arrive with damaged cans
Grab this for: A budget-friendly, high-volume wet food that gets picky puppies eating.
skip it if: Your puppy turns its nose up at wet textures and prefers crunchy kibble.
Understanding the Specs
DHA for Brain Development
DHA is an omega-3 fatty acid that supports healthy brain and eye development in growing puppies. Look for it in the guaranteed analysis, as it is a key building block during the first year of life.
Kibble Size and Shape
A Shih Tzu’s flat face and underbite make standard kibble hard to grab. Small-breed formulas use tiny pieces, and breed-specific options like Royal Canin shape the kibble to match the jaw, reducing mealtime frustration.
