The best food for a Shih Tzu puppy is a puppy-formulated recipe suited to the dog’s age and expected size. Hill’s Science Diet Small & Mini Puppy is best for small-breed growth support, while Nutro Natural Choice Puppy is a chicken-first option. Royal Canin Small Indoor Puppy is intended for qualifying indoor puppies; the two Royal Canin Shih Tzu Adult foods are for older dogs, not growing puppies.

Hill’s Science Diet Puppy Small & Mini
This dry puppy food is a strong match for buyers looking for a formula identified for small and mini puppies. Its listed features focus on several areas of development: balanced minerals support growing bones and teeth, DHA and fish oil support brain and eye development, and an antioxidant blend supports the developing immune system.
Best for: Shih Tzu owners who want a puppy-specific small-breed option with listed support for growth and development. It was selected because its life-stage and small-breed focus make it more relevant to a puppy than the adult Shih Tzu recipes below.
Consider: The provided product details do not specify an age range or expected adult-weight range. Check the package feeding directions and ask a veterinarian whether the formula suits your puppy’s current age and needs.
Nutro Natural Choice Puppy Chicken & Brown Rice
Nutro’s puppy recipe lists real chicken as its number-one ingredient and includes DHA to support brain and eye development. The product information also says it supports healthy bones and muscles, skin and coat, digestion, and immunity. It is described as made without chicken by-product meal, corn, wheat, or soy, and with non-GMO ingredients.
Best for: Buyers who prioritize a chicken-first puppy recipe and want the listed ingredient exclusions. It was selected as a second puppy-focused choice with a different stated ingredient profile from Hill’s.
Consider: Chicken is a key ingredient, so this may not be the right choice for a puppy whose veterinarian has advised avoiding it. Review the label for the full ingredient list and feeding guidance.
Royal Canin Small Indoor Puppy
This formula is described for indoor small-breed puppies from 2 to 10 months old with an expected adult weight of 9 to 22 pounds. Its listed features include vitamins E and C and other antioxidants to support immune development. A combination of prebiotics, digestible proteins, and fiber is described as helping reduce stool odor and volume.
Best for: Owners whose puppies match the stated age and expected adult-weight range and who want a product specifically described for indoor small-breed puppies. It provides clear eligibility details for comparison.
Consider: The listed weight range is specific. Confirm your Shih Tzu’s expected adult size and age before choosing it; the product information does not establish that it is appropriate for every Shih Tzu puppy.
Royal Canin Shih Tzu Adult, 2.5 lb
This breed-specific dry food is formulated for purebred Shih Tzus aged 10 months and older. Its specialized kibble shape is designed for a small breed’s short muzzle and underbite. The listed skin and coat support comes from a nutrient complex that includes EPA, DHA, and vitamin A.
Best for: Shih Tzus approaching or entering the adult life stage whose owners want a breed-specific formula. The smaller listed bag size may suit buyers comparing the adult recipe before choosing a larger bag.
Consider: This is adult food, not a puppy-formulated choice for a younger, growing dog. Follow veterinary guidance when deciding when to transition.
Royal Canin Shih Tzu Adult, 10 lb
This larger-bag version has the same stated adult Shih Tzu focus as the 2.5-pound option. It is intended for purebred Shih Tzus 10 months and older, with kibble shaped for a short muzzle and underbite. EPA, DHA, and vitamin A are listed as part of its skin and coat support complex.
Best for: Owners seeking the adult Shih Tzu formula in a larger bag. It was included to make the available size choice clear, not because its listed nutrition differs from the smaller-bag version.
Consider: Its adult life-stage designation makes it unsuitable as the default pick for a younger puppy. Compare the label and feeding directions with your dog’s age and veterinary advice.
Buying Guide: How To Choose Food For A Shih Tzu Puppy
Does the food match your puppy’s life stage?
Start with the life-stage wording on the package. Hill’s, Nutro, and Royal Canin Small Indoor Puppy are presented as puppy options. The two Royal Canin Shih Tzu products are adult foods for dogs 10 months and older. Do not choose an adult recipe for a younger puppy solely because it names the breed.
Should you choose a breed-specific or small-breed formula?
A small-breed puppy formula may suit owners looking for food described for smaller dogs. A breed-specific adult recipe may become relevant later, but the supplied Royal Canin Shih Tzu products are not puppy formulas. For the indoor puppy food, check that your dog fits its stated age and expected adult-weight range.
Which listed features matter to you?
- Choose Hill’s if its stated focus on bones, teeth, brain, eyes, and immune support aligns with your priorities.
- Compare Nutro if you want a chicken-first recipe and the listed exclusions of corn, wheat, soy, and chicken by-product meal.
- Consider Royal Canin Small Indoor Puppy if your puppy matches its stated age and weight criteria and stool odor and volume are concerns.
When should you ask a veterinarian?
Ask your veterinarian about food selection if your puppy has health concerns, a suspected food sensitivity, or growth needs that make general recommendations uncertain. Use the package’s feeding directions, and seek professional guidance before changing diets or moving from puppy food to adult food.
