Feeding a Shih Tzu well is the single biggest lever you have over its energy, coat, joints, and lifespan. The Shih Tzu is a flat-faced (brachycephalic) toy breed with prominent eyes, so anything that presses on the neck, overheats the dog, or rubs the face needs a second look. This guide walks through what actually matters when choosing the best food for a Shih Tzu, how to size and compare options, and the mistakes that trip up most owners, all without pushing any single product on you.

What to look for in a food for a Shih Tzu
- A named animal protein (chicken, beef, lamb, fish) as the first ingredient, ideally with 22-30% protein for adults
- Moderate fat (12-18%) for steady energy without pushing weight gain
- Guaranteed levels of omega-3s (EPA/DHA) and glucosamine/chondroitin for joint support
- A life-stage statement from AAFCO so the recipe is complete and balanced
- No vague ‘meat by-product meal’ as the lead ingredient and no excessive fillers
Why the Shih Tzu is different

A Shih Tzu typically weighs 9-16 lb and stands 8-11 inches at the shoulder, with a long, flowing double coat that sheds little but tangles and mats fast, often kept in a shorter ‘puppy cut’. It is an affectionate, easygoing lap dog with modest exercise needs and a stubborn streak. On top of that, the breed is prone to back and knee problems (IVDD and luxating patellas), breathing limits from the flat face, eye injuries, and dental crowding, so the right food should work with that build and those health tendencies rather than against them.

A Shih Tzu’s flat face and undershot jaw make it harder to pick up large or round kibble, so small-breed or specially shaped pieces are easier to eat and chew. Use a wide, shallow bowl so the dog does not press its face into the dish, which also cuts down on food stuck in the facial hair. Most 9-16 lb adults need only about 350-550 calories a day, so extra weight arrives quickly, and every pound makes breathing and back problems worse. Dental crowding is common in the breed, so daily tooth brushing matters more than any dental kibble claim. If you see chronic itching, ear infections, or loose stools, ask your vet about an elimination trial with a limited-ingredient diet before trying product after product.
Types of food
Dry kibble
The convenient, cost-effective default. Look for a formula sized to your dog’s life stage and kibble pieces matched to jaw size.
Fresh or gently cooked
Good for picky eaters or dogs with sensitive stomachs.
Raw or freeze-dried raw
High protein and minimal processing, but demands careful handling and a vet conversation, especially for large or deep-chested dogs.
Quick comparison
Rough daily feeding guide by weight (adult, moderate activity):
| Body weight | Approx. daily calories | Cups of kibble/day* |
|---|---|---|
| 10-20 lb | 300-450 kcal | 0.75-1.25 |
| 40-60 lb | 900-1300 kcal | 2.25-3.25 |
| 80-100 lb | 1600-2100 kcal | 4-5.25 |
| 110-135 lb | 2100-2600 kcal | 5.25-6.5 |
*Cup amounts assume a mid-calorie kibble of roughly 350-400 kcal per cup; always check your specific food’s label.
How to choose the right food
- Match the formula to size and life stage: a Shih Tzu does best on food designed for its small adult frame
- Use body-condition scoring, not the bag’s chart alone, to set portions
- Transition over 7-10 days to avoid loose stools
- Re-evaluate every few months as activity and age change
Common mistakes to avoid
- Free-feeding, which drives obesity and strains joints
- Switching foods abruptly
- Chasing marketing terms (‘grain-free’, ‘human-grade’) without checking the actual nutrient profile
Matching the food to your Shih Tzu’s life stage
Needs change as a Shih Tzu grows. In puppyhood, prioritize the right size for the current body and something forgiving, since a young Shih Tzu is still growing into the 9-16 lb adult range and re-checks every few weeks keep the fit or portion correct. Through the active adult years, durability and daily comfort matter most because this is an affectionate, easygoing lap dog with modest exercise needs and a stubborn streak. For seniors, lean toward extra support and gentleness, since older dogs feel back and knee problems (IVDD and luxating patellas) more acutely and appreciate easier handling. Buying with the whole timeline in mind saves money and spares your dog the stress of constant swaps.
Care and longevity
Whatever food you settle on, a few minutes of upkeep doubles its useful life and keeps your Shih Tzu safer. Inspect it regularly for wear, clean it on the schedule the material calls for, and store it dry to prevent odor and damage. Check the fit or suitability at least seasonally, because a Shih Tzu’s weight, coat, and activity all shift across the year. When something is frayed, cracked, outgrown, or no longer doing its job, replace it promptly rather than pushing a worn item one more month.
Frequently asked questions
How much should I feed my Shih Tzu?
Portion by calories, not habit. A Shih Tzu in the 9-16 lb range typically needs the amounts in the table above, adjusted down for spayed/neutered or less active dogs. Weigh food with a cup or scale and re-check your dog’s waistline every two weeks.
Should a Shih Tzu eat puppy food longer?
No. Small breeds like the Shih Tzu finish growing faster than large breeds, usually around 9-12 months, so switch to an adult small-breed formula at that point. Staying on calorie-dense puppy food longer mostly adds unwanted weight.
Bottom line
The best food for a Shih Tzu is the one that fits your individual dog’s size, coat, and temperament, is built to handle a small frame, and supports the breed’s known health needs. Measure first, prioritize safety and durability over price or looks, and re-check the fit as your dog grows and ages. Get those fundamentals right and you will spend once instead of three times.
