Key takeaways

  • Protein source: Named meat or fish, with the amount appropriate for age and activity.
  • Fat and omega fatty acids: Support skin and coat, which matters for the Shih Tzu’s long hair.
  • Fiber and carbohydrate sources: Digestible grains or vegetables are fine for most dogs unless a vet advises otherwise.
  • Calorie density: Listed in kcal per cup or per kilogram; helps with portion control.
  • No unnecessary artificial colors: Your dog does not care what color the kibble is.

Shih Tzus do best on a complete, balanced food with a small kibble size, moderate calories, and quality protein. Look for an AAFCO “complete and balanced” statement for your dog’s life stage, a named animal protein first, and avoid overfeeding, since this breed gains weight easily. Ask your veterinarian before changing diets.

What Makes Shih Tzus Different

Shih Tzus are small dogs, typically in the range of 9 to 16 pounds, with flat faces, long coats, and a tendency toward dental crowding. Their small mouths make bite-size kibble easier to pick up, and their compact frames mean a few extra treats can add up quickly. Breed-associated concerns can include sensitive skin, food allergies, dental disease, and certain urinary or eye issues, though every dog is different and your vet is the right person to ask about your dog.

Reading the Label

Start with the nutritional adequacy statement. Look for wording that says the food is complete and balanced for your dog’s life stage, backed by AAFCO feeding trials or formulated to meet AAFCO nutrient profiles. Then read the ingredient list. Named proteins like chicken, salmon, or lamb should appear near the top. Be cautious about vague terms and marketing buzzwords; “premium” and “natural” do not have strict definitions on their own.

Freeze-dried / raw Appealing to some dogs Handling and safety considerations Only with veterinary advice

Puppy, Adult, and Senior Needs

Puppies need food formulated for growth, with sufficient protein, fat, and calcium for their size. A small-breed puppy formula is commonly recommended. Adults usually do well on a maintenance diet, and seniors may benefit from lower calories and joint-supporting ingredients. Check the label for the life-stage statement, and ask your vet when to switch. Transition gradually over about a week by mixing increasing amounts of new food with the old to avoid stomach upset.

Skin, Coat, and Allergy Considerations

Many Shih Tzus have sensitive skin. Itching, redness, ear infections, or digestive upset can point to food or environmental allergies, but only a veterinarian can diagnose the cause. If a vet suggests an elimination diet, follow the plan strictly. Limited-ingredient and hydrolyzed formulas exist for this purpose, and a prescription may be needed for some.

Popular brands often discussed by owners include Royal Canin (which sells breed-specific Shih Tzu formulas), Hill’s Science Diet, Purina Pro Plan, and Blue Buffalo. Compare current formulas and feed guidelines. You can browse Royal Canin Shih Tzu food or small breed dry dog food to see the range.

Portion Control and Treats

Weight management is essential. Use the feeding guide on the bag as a starting point and adjust based on body condition. You should feel ribs under a thin layer of fat. Measure meals with a cup rather than guessing, and count treats toward daily calories. Many vets suggest treats make up only a small fraction of intake. Use small, low-calorie rewards for training, and consider a slow feeder bowl for small dogs if yours eats too fast.

Consider the bowl and feeding spot, too. Shih Tzus have flat faces, so a shallow, wide bowl is easier to eat from than a deep one. Keep the long facial hair out of the bowl with a topknot or regular trimming, and wipe the beard after meals to prevent staining and skin irritation. Consistent feeding times and a calm environment help sensitive stomachs.

Dental Care Matters

Small breeds are prone to dental problems. Kibble alone does not replace brushing. Ask your vet about daily brushing, dental chews that meet recognized standards, and regular checkups. Choose appropriately sized chews and supervise to avoid choking.

Mistakes to Avoid

  1. Switching foods abruptly.
  2. Free-feeding, which encourages weight gain.
  3. Choosing foods based on trendy buzzwords instead of the nutritional statement.
  4. Ignoring the calorie count of treats and table scraps.
  5. Forgetting fresh water access.

Storage affects freshness. Keep kibble in its original bag inside an airtight container, away from heat and moisture, and use it within the window on the label. Note the lot number in case of recalls, and buy bag sizes that your small dog can finish before the food goes stale.

Finally, watch your dog rather than the bag. Healthy signs include steady energy, a shiny coat, firm stools, and a stable weight. If you see persistent itching, loose stools, or changes in appetite, call your veterinarian instead of rotating through brands.
