Shih Tzu Diet and Nutrition Feeding Guide

A healthy Shih Tzu diet should be built around small-breed dog food, controlled portions, steady meal times, and easy-to-digest ingredients. Because Shih Tzus are small, brachycephalic dogs with lower daily calorie needs, even slight overfeeding can lead to weight gain, breathing discomfort, digestive issues, and reduced energy.

Most adult Shih Tzus need about 300 to 460 calories per day, depending on weight, activity level, age, and body condition. A typical adult Shih Tzu usually eats about ¾ to 1½ cups of dry food per day, split into two meals, but the exact amount depends on the calorie density of the food.

This Shih Tzu diet and nutrition guide explains what to feed, how much to feed, how often to feed, and how to adjust meals for puppies, adults, seniors, picky eaters, and dogs with sensitive stomachs.

What to Feed a Shih Tzu: Diet and Nutrition Needs

Feeding a Shih Tzu is not about choosing the most expensive food. It is about choosing food that matches a small dog’s calorie needs, sensitive digestion, small mouth, coat health, and tendency to gain weight. The best food for a Shih Tzu is usually a complete and balanced small-breed formula that is easy to chew, easy to digest, and not too high in calories.

Shih Tzus often look naturally fluffy, which can hide early weight gain. By the time extra fat is obvious, the dog may already be carrying too much strain on the joints, breathing system, and heart. On the other side, poor-quality food or underfeeding may show up as low energy, dull coat, loose stool, tear staining, or picky eating.

A good Shih Tzu diet should support stable weight, firm stools, healthy skin, a soft coat, steady energy, and comfortable chewing.

Basic Dietary Needs of a Shih Tzu

Shih Tzus need food that supports lean muscle, digestion, coat health, dental comfort, and long-term weight control. They do not need extreme protein, very rich food, or large portions. Balance matters more than high numbers.

• Lean animal protein for muscle and coat support
• Moderate fat for energy without excess weight gain
• Digestible carbohydrates for steady energy
• Fiber for healthy stool quality
• Small kibble or soft texture for easier chewing
• Controlled calories to prevent obesity

Too much food, too many treats, or food that is too rich can quickly cause weight gain, gas, loose stool, or picky eating in this breed.

Ideal Nutrient Balance for Shih Tzus

The ideal Shih Tzu diet should provide enough protein for muscle and coat health, but not so much fat or calories that weight becomes difficult to manage.

Nutrient	Recommended Range	Why It Matters for Shih Tzus
Protein	22–28%	Supports lean muscle, coat quality, and healthy growth
Fat	10–16%	Provides energy while helping reduce excess weight gain
Carbohydrates	Moderate	Supports daily energy and digestion
Fiber	3–5%	Helps stool quality and digestive regularity
Moisture	Moderate to high	Supports hydration, digestion, and easier chewing

Best Food Types for Shih Tzus

Different food types can work for Shih Tzus, but each has strengths and weaknesses. The right choice depends on your dog’s teeth, digestion, appetite, weight, and daily routine.

Food Type	Best For	Main Caution
Dry kibble	Easy storage, portion control, dental crunch	Can be too hard or too dry for some Shih Tzus
Wet food	Picky eaters, seniors, dogs needing more moisture	Can add calories quickly if not measured
Fresh food	Dogs needing softer, highly digestible meals	Higher cost and shorter storage life
Freeze-dried food	Convenience with concentrated nutrition	Often needs rehydration and careful portion control
Homemade food	Ingredient control for specific needs	Can become unbalanced without professional guidance

Kibble Size and Texture Matter for Shih Tzus

Shih Tzus have small mouths, short muzzles, and compact jaws. Large or very hard kibble may be difficult to chew and can lead to food refusal, gulping, or choking risk. Small-breed kibble, softened kibble, wet food, or mixed textures are often easier for Shih Tzus to eat comfortably.

How to Choose Dog Food for a Shih Tzu

When choosing food for a Shih Tzu, focus on clear ingredients, small-breed suitability, digestibility, and calorie control. Avoid choosing food only because it says “premium,” “natural,” or “breed inspired.” The food still needs to match your dog’s body condition and digestion.

Label Item	What to Look For	What to Avoid
Formula type	Small breed, puppy, adult, senior, or weight control as needed	Generic food that does not match life stage
Protein source	Named animal protein such as chicken, turkey, fish, beef, or lamb	Vague wording like “animal protein”
Fat level	Moderate fat for controlled calories	Very rich food if your dog gains weight easily
Kibble size	Small pieces or soft texture	Large, hard kibble that is difficult to chew
Feeding guide	Clear calorie and portion information	No calorie guidance or vague serving advice

How Much Food Should I Feed My Shih Tzu?

Most adult Shih Tzus need measured meals, not free-feeding. A typical adult Shih Tzu eats about ¾ to 1½ cups of dry food per day, split into two meals. Smaller, less active dogs may need less, while larger or more active Shih Tzus may need more.

The safest way to decide how much to feed is to start with calories, then convert those calories into cups or grams based on the food label. Cup measurements are not exact because one food may contain far more calories per cup than another.

Why Portion Control Is Important for Shih Tzus

Shih Tzus are small dogs, so a few extra bites each day can become a large calorie surplus over time. Free-feeding, oversized treats, table scraps, and unmeasured scoops are common reasons Shih Tzus gain weight.

Signs your Shih Tzu may be eating too much include:

• Weight gain or a round belly
• No visible waist when viewed from above
• Heavy breathing after light activity
• Less interest in play or walks
• Begging even after meals
• Difficulty feeling the ribs under the coat

Shih Tzu Daily Calorie Needs by Weight

Daily calorie needs depend on body weight, age, activity level, metabolism, and whether your Shih Tzu needs to lose, gain, or maintain weight. Use this chart as a starting point, then adjust based on body condition.

Shih Tzu Weight	Low Activity	Normal Activity	High Activity
8 lb (3.6 kg)	250–300 kcal/day	300–340 kcal/day	350–380 kcal/day
10 lb (4.5 kg)	300–340 kcal/day	340–380 kcal/day	380–420 kcal/day
12 lb (5.4 kg)	340–380 kcal/day	380–420 kcal/day	420–460 kcal/day
14 lb (6.4 kg)	380–420 kcal/day	420–460 kcal/day	460–500 kcal/day

These are general feeding estimates. If your Shih Tzu is overweight, underweight, pregnant, nursing, very young, senior, or has a medical condition, portion changes should be made carefully.

How Much Dry Food Does a Shih Tzu Need?

How Much Wet Food Should a Shih Tzu Eat a Day?

The amount of wet food a Shih Tzu should eat depends on the calories in the can, tray, or pouch. Wet food usually contains fewer calories per ounce than dry food because it has more moisture, but portions can still add up quickly if they are not measured.

Most adult Shih Tzus need about 300 to 460 calories per day. To calculate wet food portions, check the label for calories per can or calories per ounce, then divide your dog’s daily calorie target into two meals.

Wet Food Feeding Example for Shih Tzus

Daily Calorie Need	If Wet Food Has 100 kcal Per 3 oz	Suggested Meal Split
300 kcal/day	About 9 oz per day	4.5 oz per meal
380 kcal/day	About 11–12 oz per day	5.5–6 oz per meal
460 kcal/day	About 13–14 oz per day	6.5–7 oz per meal

This is only an example. Some wet foods are much richer than others, so always use the calorie label instead of guessing by can size.

Can You Mix Wet and Dry Food for a Shih Tzu?

Yes, Shih Tzus can eat a mix of wet and dry food. Mixed feeding can help picky eaters, seniors, dogs with chewing trouble, or Shih Tzus that need more moisture in their diet. The key is to reduce the dry food when adding wet food so the total calories stay controlled.

For example, if you add wet food to your Shih Tzu’s bowl, do not keep the same full dry food portion. Replace part of the dry food with wet food based on calories. This helps prevent accidental overfeeding.

A simple mixed-feeding rule is: add calories from wet food, then subtract the same amount of calories from dry food. This keeps the meal balanced and helps your Shih Tzu maintain a healthy weight.

Dry food amounts depend on calories per cup. Many small-breed dry foods contain around 350 to 450 calories per cup, so two foods with the same cup amount can deliver very different calories. Always check your food label before deciding the final portion.

Shih Tzu Feeding Amount Guide by Weight

The table below gives a practical starting point for how much dry food to feed a Shih Tzu per day. These amounts assume a dry food with about 350–450 calories per cup. If your dog food is higher or lower in calories, adjust the portion using the label.

Shih Tzu Weight	Daily Dry Food Amount	Approx. Grams Per Day	Meals Per Day
8 lb	¾ to 1 cup	70–95 g	2 meals
10 lb	1 to 1¼ cups	95–120 g	2 meals
12 lb	1¼ to 1½ cups	120–145 g	2 meals
14 lb	1½ to 1¾ cups	145–165 g	2 meals

This feeding chart is only a starting point. A lazy indoor Shih Tzu may need less food, while a very active dog may need slightly more. Always use body condition, weight changes, stool quality, and energy level to adjust the final amount.

How Often Should a Shih Tzu Eat?

Most adult Shih Tzus should eat two measured meals per day. Puppies need smaller meals more often because their stomachs are small and they use energy quickly. Seniors may also do better with smaller, softer meals if chewing or digestion becomes harder.

Shih Tzu Feeding Frequency by Life Stage

Life Stage	Meals Per Day	Best Feeding Approach
Puppy, 2–6 months	3–4 meals	Small, frequent meals to support growth and steady energy
Puppy, 6–12 months	3 meals	Measured meals while slowly preparing for adult feeding
Adult	2 meals	Morning and evening meals for weight control
Senior	2 smaller meals	Easy-to-chew food with careful calorie control

Free-feeding is not recommended for most Shih Tzus. Leaving food out all day makes it harder to control calories and often leads to weight gain, picky eating, or irregular appetite.

Use Body Shape, Not Just the Bowl, as Your Guide

Your Shih Tzu’s body condition is more important than the amount listed on a bag of food. The right portion should keep your dog lean, active, and comfortable.

Your Shih Tzu should:

• Have a visible waist when viewed from above
• Have ribs you can feel easily but not see sharply
• Move comfortably without heavy breathing after light activity
• Maintain steady weight from week to week
• Have firm, regular stools

If your Shih Tzu gains or loses weight, adjust food slowly over 1–2 weeks instead of making sudden large changes.

Shih Tzu Puppy, Adult, and Senior Feeding Guidelines

Shih Tzus need different feeding routines at different ages. A puppy needs more frequent meals for growth, an adult needs strict portion control, and a senior often needs easier-to-digest food with fewer calories. Feeding the same way at every life stage can lead to weight gain, stomach problems, low energy, or picky eating.

Shih Tzu Puppy Feeding Guide

Shih Tzu puppies grow quickly and need food made for small-breed puppies. Their stomachs are small, so they should not be expected to eat one or two large meals. Most puppies do better with three to four smaller meals per day.

Good feeding tips for Shih Tzu puppies:

• Choose food made for small-breed puppies
• Feed 3–4 small meals per day from 2–6 months
• Feed about 3 meals per day from 6–12 months
• Do not skip meals, especially in young puppies
• Keep treats very small and limited
• Soften kibble if chewing is difficult

Puppy food should support growth, bone development, brain development, and steady energy without causing rapid weight gain.

Adult Shih Tzu Feeding Guide

Adult Shih Tzus usually need fewer calories than puppies. This is the stage where overfeeding becomes the biggest risk. Most adult Shih Tzus do well with two measured meals per day instead of free-feeding.

Adult feeding tips:

• Feed two measured meals per day
• Use a small-breed adult formula
• Choose weight-control food if your dog gains weight easily
• Limit treats to less than 10% of daily calories
• Adjust portions based on activity level and body shape
• Measure food with a proper cup or kitchen scale

For most adult Shih Tzus, consistent meal timing and measured portions are more important than changing food brands often.

Senior Shih Tzu Feeding Guide

Senior Shih Tzus often move less, burn fewer calories, and may have weaker teeth or slower digestion. They still need quality protein, but portions may need to be smaller to prevent weight gain.

Senior feeding tips:

• Use slightly lower calories if activity has dropped
• Choose easy-to-digest protein sources
• Add moisture with wet food or softened kibble if chewing is difficult
• Keep meals smaller and consistent
• Watch for sudden appetite or weight changes
• Avoid high-fat table scraps

Older dogs still need balanced nutrition. The goal is not simply “less food,” but the right food in the right amount for their age, teeth, digestion, and weight.

Shih Tzu Feeding Needs by Life Stage

Life Stage	Calories	Protein Needs	Meals Per Day	Common Mistake
Puppy	Higher	Moderate to high	3–4 meals	Skipping meals or using adult food too early
Adult	Moderate	Moderate	2 meals	Too many treats or unmeasured portions
Senior	Often lower	Moderate	2 smaller meals	Overfeeding after activity decreases

Treats and Snacks for Shih Tzus

Treats are fine for Shih Tzus, but they add calories quickly. Because this breed is small, even a few extra treats each day can affect weight over time.

Good treat rules:

• Keep treats under 10% of daily calories
• Break treats into tiny pieces for training
• Avoid daily table scraps
• Use low-calorie treats if your Shih Tzu gains weight easily
• Reduce meal portions slightly when giving extra treats

Safe and Unsafe Foods for Shih Tzus

Some human foods are safe for Shih Tzus in small amounts, while others are dangerous or toxic. Safe foods should still be treated as occasional extras, not the main diet.

Safe vs Unsafe Foods for Shih Tzus

Safe in Small Amounts	Unsafe or Toxic
Cooked plain chicken	Chocolate
Plain cooked rice	Grapes and raisins
Plain pumpkin	Onions and garlic
Carrots	Xylitol or sugar-free foods
Apple slices without seeds	Alcohol
Plain cooked egg	Macadamia nuts
Green beans	Cooked bones

Chicken and rice can be safe for many Shih Tzus when plain and properly cooked, but they should not replace a complete diet every day unless your veterinarian gives a specific plan. When in doubt, do not feed a human food to your dog.

Can Shih Tzus Eat Homemade Food?

Shih Tzus can eat homemade food, but it must be balanced. Plain chicken, rice, pumpkin, carrots, eggs, and some vegetables may be safe ingredients, but a homemade diet can easily miss important nutrients if it is not planned correctly.

Homemade food is best used as an occasional topper or as part of a professionally planned diet. It should not become the full-time diet unless it includes the right balance of protein, fat, carbohydrates, vitamins, and minerals.

Water Matters Too

Shih Tzus should always have clean, fresh water available. Wet food or adding warm water to kibble can help dogs that do not drink enough, chew poorly, or have dry stools.

Special Diets, Feeding Problems, and When to See a Vet

Some Shih Tzus need special feeding adjustments because of sensitive stomachs, food allergies, skin problems, tear staining, obesity, dental issues, or age-related changes. The right solution depends on the cause, not just the symptom.

Special Diet Needs in Shih Tzus

A Shih Tzu may need a special diet if regular food causes repeated digestive problems, itching, weight gain, or appetite issues.

Common reasons include:

• Food allergies or food sensitivity
• Sensitive stomach or frequent diarrhea
• Skin itching or recurring ear problems
• Tear staining that may be linked to diet sensitivity
• Weight gain or obesity
• Dental trouble or difficulty chewing
• Low appetite or low energy in older dogs

In these cases, a limited-ingredient food, sensitive-stomach formula, small-breed senior food, dental-friendly texture, or weight-control food may help. Avoid changing foods repeatedly without tracking symptoms, stool quality, and body weight.

Common Shih Tzu Feeding Problems and Solutions

Problem	Possible Cause	What You Can Do	When to See a Vet
Picky eating	Too many treats, frequent food changes, dental discomfort	Use set meal times and reduce extras	If appetite drops suddenly or weight decreases
Always hungry	Unbalanced portions, habit begging, too many snacks	Measure food and use low-calorie snacks	If hunger comes with weight loss or behavior change
Loose stool	Fast food change, rich food, sensitivity	Switch food slowly and remove table scraps	If diarrhea lasts more than 24–48 hours
Weight gain	Too many calories, low activity, free-feeding	Reduce portions gradually and track weight	If breathing, mobility, or energy worsens
Not eating	Stress, dental pain, illness, stomach upset	Monitor closely and offer fresh food	If your dog refuses food for more than 24 hours
Bad breath or chewing trouble	Dental disease or painful teeth	Use softer textures temporarily	If chewing pain, drooling, or mouth odor persists

How to Switch Shih Tzu Dog Food Safely

Changing food too fast is one of the most common causes of loose stool, gas, and food refusal. Most Shih Tzus do better with a slow transition over 7–10 days.

Safe switching steps:

• Days 1–2: 75% old food and 25% new food
• Days 3–4: 50% old food and 50% new food
• Days 5–6: 25% old food and 75% new food
• Day 7 onward: 100% new food if stool and appetite are normal

Slow the transition if your Shih Tzu develops soft stool, gas, vomiting, itching, or refuses meals.

Shih Tzu Diet and Nutrition FAQs

How much food should a Shih Tzu eat per day?

Most adult Shih Tzus eat about ¾ to 1½ cups of dry food per day, split into two meals. The exact amount depends on body weight, activity level, age, body condition, and calories per cup.
