Picking dinner for a Shih Tzu is different than feeding most other dogs. That short muzzle, the underbite, the tiny mouth — all of it means the shape and size of the kibble matter as much as what is inside the bag. A giant pellet you would feed a Lab just does not work here.
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.
Your Shih Tzu’s flat face and small jaw make eating tricky — the wrong kibble can cause gagging or poor digestion. The best dog food for shih tzu solves that with a small kibble shape (or a soft wet food texture), gentle ingredients, and a texture that works for puppies, picky adults, and seniors alike.

How To Choose The Best Dog Food for Shih Tzu
Shih Tzus are brachycephalic — that just means they have a flat face and a short muzzle. Their jaw structure makes chewing certain kibble shapes genuinely hard. On top of that, many Shih Tzus have sensitive skin and a picky appetite. Here is what matters most.
Match the Kibble to the Mouth
A standard round pellet might be too large or too hard for a Shih Tzu to pick up. Look for a small kibble or a unique shape designed for a brachycephalic bite. Some brands shape the pellet specifically for the Shih Tzu’s underbite so they can grab it without dropping pieces.
Look for Skin and Coat Nutrition
Your Shih Tzu’s long, double coat needs specific fatty acids to stay shiny and healthy. You want ingredients rich in Omega-3 and Omega-6 fatty acids, and sometimes added vitamin E. This helps reduce dry skin and makes that coat easier to manage.
Decide on Wet Food vs. Dry Kibble
Dry kibble is best for most meals because it helps reduce tartar build-up on teeth. Wet food, like the Loaf in Sauce options, works well for picky eaters or older dogs who struggle to chew hard food. You can also mix a little wet food into dry kibble to entice a fussy pup.

In‑Depth Reviews
1. Royal Canin Breed Health Nutrition Shih Tzu Puppy Dry Dog Food, 2.5 lb Bag
The only pick designed specifically for a Shih Tzu’s short muzzle and underbite.
This is the one formula on the list built from the ground up for a purebred Shih Tzu puppy from 8 weeks to 10 months old. The unique kibble shape is not a marketing gimmick — it is shaped so a puppy with a brachycephalic jaw (that flat face) can actually pick it up without struggling. It also includes an antioxidant complex, including vitamin E, to support the development of a growing immune system.
Buyers report that their Shih Tzu female ate this for over six months, and her weight climbed from a frail 3 lbs to a healthy 11.5 lbs at almost one year old. That is a strong sign that the high-quality proteins and prebiotics in this 2.5 lb bag support healthy growth and good stool quality. The bag is small compared to some options, but for a puppy, it is the right starting portion.
Unlike the Hill’s Science Diet which is a general small-breed formula, this Royal Canin product targets the specific shape and coat needs of a Shih Tzu. It promotes healthy skin and that long coat with specific nutrients, and it helps reduce stool odor thanks to the prebiotic fiber.
Shih Tzu breed formula: The kibble shape and nutrient profile are engineered for the Shih Tzu’s mouth and coat, which is a level of specificity you do not get with general small-breed bags.
Puppy size only: This is strictly for puppies (under 10 months), so you will need to switch to the adult formula later.
breed-first design: You have a Shih Tzu puppy and want a food that perfectly fits their face and supports healthy weight gain.
puppy size only: Your dog is over 10 months old or you want a larger, more cost-effective bag.
2. Hill’s Science Diet Adult Sensitive Stomach & Skin Small & Mini Dry Dog Food, 4 lb Bag
The gentle formula that fixes upset stomachs while keeping the coat shiny.
If your Shih Tzu has a sensitive stomach or itchy skin, this 4 lb bag is the first place to look. The small kibble is perfect for miniature and small breeds, and the highly digestible formula is packed with prebiotic fiber so nutrients get absorbed easily instead of causing loose stool.
Owners mention that the small kibble is ideal for miniature dachshunds and that it resolves stomach issues and produces a shiny coat. Another reviewer with toy poodles said it resolved skin allergies. For your Shih Tzu, the addition of omega-3 and omega-6 fatty acids (essential fats that help skin and fur) combined with vitamin E directly supports that long coat. It is also complete and balanced with 27 key nutrients for adult dogs aged 1-6.
The trade-off? The chicken flavor might not be a hit with every picky Shih Tzu. One reviewer noted their dog lost interest in eating it quickly. It also does not have a breed-specific kibble shape like the Royal Canin Shih Tzu line.
Sensitive stomach aid: The triple support for stomach, skin, and immune system is backed by real reviews showing it stops digestive upset and improves fur quality.
Chicken aversion risk: Some Shih Tzus are picky; the chicken flavor may need a topper for stubborn eaters.
tummy and coat fix: Your adult Shih Tzu has chronic soft stool or dry, itchy skin.
chicken aversion risk: Your dog turns up its nose at chicken-flavored food.
3. Open Farm Ancient Grains Dry Dog Food for Small Breeds, 4lb Bag
The transparent ingredient list that lets you trace every single source.
Open Farm stands out because you can trace every ingredient in the bag back to its geographic origin. The dog food is 90% animal protein from humanely-raised chicken and turkey, blended with ancient grains like oats and quinoa. These unrefined grains are often recommended for dogs with sensitive stomachs or legume and potato sensitivities — which is common among Shih Tzus.
This is a complete and balanced formula for all life stages, but it is specifically marketed for small breeds. It is free of peas, potatoes, and legumes, and uses non-GMO fruits, veggies, and superfoods like pumpkin and coconut oil. Customers note their little Havanese and other small dogs love it, and the brand is trusted for its quality formulation by a PhD in animal nutrition.
Compared to the Bil-Jac option, this has a harder crunch texture rather than a soft crumble. The “pellet” form is still small, but if your Shih Tzu has missing teeth or a very weak jaw, a wet food or the Bil-Jac soft bite might be easier to manage.
Traceable ingredient sourcing
- 100% traceable ingredients
- High protein and fiber for energy
- Humanely raised chicken
One consideration
- Pellet texture might be hard for seniors with dental issues
traceable excellence: You want to know exactly where your dog’s food comes from and prefer a grain-inclusive recipe.
one consideration: Your Shih Tzu needs a super soft, crumbly kibble texture.
4. Wellness CORE+ Small Breed Adult Dry Dog Food with Freeze Dried Pieces, 4 lb Bag
The protein punch that satisfies picky Yorkies and Shih Tzus alike.
This is a high-protein, nutrient-dense kibble that combines small bites with 100% raw freeze-dried turkey pieces. The idea is simple: you get the crunch of kibble with the real meat taste of freeze-dried pieces mixed in, which is often enough to convince a stubborn eater to finish their bowl. It is made with no corn, wheat, or soy, and includes prebiotics and probiotics for digestive health.
Reviewers point out that a picky Yorkie has eaten this for two years and likes both varieties. The formula includes glucosamine for joint support, omega fatty acids for a healthy coat, and taurine for heart health. However, one buyer mentioned that the freeze-dried pieces are very few, and the bag picture is somewhat deceptive regarding the quantity of those pieces. Another pointed out the kibble is a little big for a 7.5 lb multi-poo, so it might still be large for a Shih Tzu’s tiny mouth depending on the individual dog.
Unlike the Royal Canin Shih Tzu line, this is a general “All Breed Sizes” formula despite being marketed for small breeds. The bite size might be slightly larger than the breed-specific shape of the Royal Canin.
Protein and probiotics
- High protein for lean muscle
- Probiotics for digestive health
- Natural ingredients with no fillers
Two minor quirks
- Freeze-dried pieces are fewer than pictured
- Kibble size may be borderline for tiny mouths
protein and probiotics: Your Shih Tzu needs a high-protein boost and loves freeze-dried meat toppers.
two minor quirks: Your dog has a very small mouth and needs the smallest possible kibble size.
5. Tender & True Pet Nutrition Small Breed Organic Chicken Recipe Dog Food, 4 lb
The organic bite-size kibble that is gentle on tiny mouths and missing teeth.
If you prioritize organic ingredients and humane farming, this 4 lb bag is the standout. It is USDA Organic Certified, meaning the first ingredient is cage-free USDA organic chicken raised without antibiotics. The bite-size kibble is specifically designed for small breed dogs, and shoppers say it is ideal for 16-lb dogs with small mouths and missing teeth — which is a common challenge for senior Shih Tzus.
This grain-free recipe has no corn, wheat, or soy, and it is made by a company that is GAP humane certified. It is complete and balanced for young adult dogs. However, there is a significant availability issue: one long-time buyer noted they have not been able to get it for two months because it is more frequently out of stock than in stock. This could be a deal-breaker if you depend on auto-shipments.
Compared to the significantly heavier Bil-Jac (30 lbs), this is a smaller bag at 4 lbs. That makes it great for trial runs but less convenient as a long-term staple unless you can reliably restock.
Clean organic nutrition
- USDA Organic and GAP humane certified
- Bite-size kibble great for seniors with missing teeth
- No fillers, corn, wheat, or soy
Supply risk
- Frequently out of stock on Amazon
- Only 4 lb bag size available
clean organic nutrition: You want USDA organic certification and have a senior Shih Tzu with dental issues.
supply risk: You need a guaranteed consistent supply or a larger bag size.
6. Bil-Jac Small Breed Adult Dry Dog Food, Chicken & Oatmeal & Yams Recipe, 30 lb
The slow-cooked, soft kibble that crumbles under pressure for tiny teeth.
This is a completely different texture from the usual hard crunch. Bil-Jac uses a unique slow-cook process to create a porous, softer kibble that crumbles when you squeeze it. For a Shih Tzu with a sensitive mouth or small teeth, this makes a real difference. A buyer with a Yorkie confirmed that the pellets crumble easily and the dog loves the flavor — even when mixed with water to soften it for a toothless dog.
The first ingredient is fresh, never-frozen chicken. The recipe also includes oatmeal and yams for slow-release carbohydrates to fuel the fast metabolism of small breeds like Shih Tzus. The company has been making dog food in the USA since 1947, and they avoid spraying fat on the outside of the kibble (which can be messy and unhealthy).
The main trade-off is bag size and dust. At 30 lbs, this is the largest bag on the list, which is great for value but can be hard to store. One owner reported that the large bag had a lot of dust from broken pellets; a smaller 6 lb bag was better packed. If you have a wood floor, the oily nature of the food might require a quick wipe up after feeding.
Tooth-friendly texture
- Soft, crumbly kibble is easy for small mouths
- Fresh chicken is the #1 ingredient
- 30 lb bag offers best value per pound
Handling headaches
- Large bag can have excess dust from broken bits
- Oily texture can be messy on floors
tooth-friendly texture: Your Shih Tzu has dental sensitivity or struggles with hard kibble.
handling headaches: You have limited storage space or dislike any mess from oily kibble dust.
7. Royal Canin Breed Health Nutrition Shih Tzu Adult Loaf in Sauce Dog Food, 3 oz (Pack of 24)
The wet food that even a stubborn Shih Tzu will actually finish.
This is the wet food alternative from the Royal Canin Shih Tzu line, designed specifically for adult dogs 10 months and older. It comes in a Loaf in Sauce format — a smooth pate that is easy for a flat-faced dog to lap up without frustration. The recipe includes an exclusive complex of nutrients including EPA, DHA, and vitamin A to support skin health and that signature coat.
Buyers with extremely picky dogs report success: one customer observed their stubborn 4-year-old Shih Tzu loves this food after an accidental purchase. Another reviewer noted their picky girl eats this more than any other wet food. The recipe also includes taurine and L-carnitine for heart health, as well as targeted sodium levels.
Unlike dry kibble, this wet food has a soft, loaf-like texture that is easier for a Shih Tzu with missing teeth or a sore mouth to chew. It is not a complete meal replacement for everyone — one reviewer called it a “complement food.” You can feed it alone, but many owners use it as a flavorful topper over dry kibble to entice a picky eater. The pack of 24 cans (3 oz each) is designed for storage convenience, though it takes up more shelf space than a bag of dry food.
Stubborn dog approved: Multiple reviews confirm that the tastiest, pickiest Shih Tzus will eat this Loaf in Sauce, which is a huge win for stressed owners.
Wet food only: It is a wet food, so it does not provide the dental benefit of crunching dry kibble; mixing it with Royal Canin dry food is often the better call.
stubborn dog approved: You have a picky adult Shih Tzu who refuses dry kibble or needs a wet topper to finish a meal.
wet food only: You only want dry kibble for dental health or need a budget-friendly every-meal option.
Understanding the Specs
Kibble Shape and Size
“Small breed” on the bag label is a good start, but a Shih Tzu needs more than just “small.” Their short muzzle and underbite mean they need a unique shape they can grab. The Royal Canin Shih Tzu line has a kibble designed specifically for that bite. If that is not available, look for very small bites that are not too hard — the Bil-Jac soft kibble is another excellent option for tiny jaws.
Protein and Fat Content
Shih Tzus have a fast metabolism and need high-quality protein for energy and muscle tone. Look for real meat (chicken, turkey, or fish) as the first ingredient. The Wellness CORE+ line is a high-protein option, while the Hill’s Science Diet balances protein with prebiotic fiber for sensitive stomachs. Fat content is also important — you want enough omega-3 and omega-6 fatty acids (healthy fats) to support that long, double coat.
Life Stage and Unique Needs
Puppy formulas (like the Royal Canin Shih Tzu Puppy) have higher calories and specific nutrients for growth. Adult formulas focus on maintenance and coat health. Senior Shih Tzus often benefit from softer textures (Bil-Jac or wet food) and ingredients that support joint health. Always match the food to the dog’s age and any specific issues like skin allergies or a sensitive stomach.

Final Thoughts: The Verdict
For most Shih Tzu owners, the dog food for shih tzu winner is the Hill’s Science Diet Sensitive Stomach because it targets the two biggest complaints (digestive upset and coat health) in a small kibble that works for the breed. If you want a shape perfectly matched to the Shih Tzu’s jaw, grab the Royal Canin Shih Tzu Puppy. And for a senior or picky adult who needs a soft texture, the Royal Canin Shih Tzu Adult Loaf in Sauce is the gentlest option — its 3 oz can size means less waste per meal.
