What to Feed Shih Tzu Dogs? | A Simple Feeding Plan

Feeding a Shih Tzu looks simple until you’re standing in the pet food aisle. These little dogs have fast metabolisms, picky tendencies, and a real risk of weight gain. The answer isn’t one magic brand but a system: pick the right type of food, feed the right amount, and stick to a routine. Here’s the practical breakdown.

The Right Food: Complete, Balanced, and Small-Breed Sized

The safest general answer is to feed a complete-and-balanced commercial dog food formulated for your Shih Tzu’s life stage and small-breed size. Look for an AAFCO statement on the package—that label confirms the food meets nutritional standards for the dog’s age group.

A protein-forward formula is a smart starting point. Many breed guides also advise avoiding foods heavy in fillers such as corn, wheat, or soy, especially for sensitive dogs.

Why small-breed-specific food? Shih Tzus have small mouths and benefit from small kibble that’s easy to chew. These formulas also tend to be calorie-dense, so your dog gets the nutrition they need in smaller portions.

How Much Should a Shih Tzu Eat Per Day?

Portion sizes vary by weight, age, activity, metabolism, and food type—there’s no single universal amount.

Here’s what that looks like in practice for healthy adult Shih Tzus:

Meal Timing: Two Meals a Day, No Free-Feeding

Adult Shih Tzus should eat two meals per day, roughly 10–12 hours apart—one in the morning and one in the early evening. This routine supports digestion and steady energy, and it helps you catch appetite changes early.

Puppies need more frequent meals. Under six months, feed three meals per day; some guides suggest four smaller meals for very young puppies. After six months, transition to two meals daily.

Common Feeding Mistakes and How to Adjust

Overfeeding is the top risk for Shih Tzus, a breed prone to obesity. Feeding a generic cup amount without checking your dog’s actual weight and body condition is the most common error.

The body-condition check is simple: you should be able to feel your dog’s ribs easily without pressing hard.

Adjustments also matter based on your dog’s status. Always use age-appropriate formulas—don’t feed a puppy growth diet long-term unless your veterinarian advises it.

One more consideration: if you’re tempted by home-cooked meals, options like boiled chicken, plain rice, and cooked vegetables exist, but the cited sources aren’t veterinary formulation guidelines. A complete-and-balanced commercial diet remains the safest default, with vet guidance for any medically tailored plan.
