Shih Tzu were bred to spend their days in palaces, cuddling up to their owners — meaning they’re not the most active dogs. 

My Shih Tzu fits this criteria. He also has epilepsy, which has affected his energy levels and his ability to exercise. He can’t overheat, because that can trigger a seizure, so extensive activity is out of the question.

However, his medication causes him to need more sleep, so he tends to eat more than he can burn off. 

Due to this, he ballooned in weight during the first few years of his life, eventually weighing in at about 18 pounds (which is 5 pounds overweight for his size, the equivalent of an extra 40 pounds on my 5’0 frame). 

And he’s not alone. 

Many Shih Tzu can have obesity problems, especially due to their sedentary lifestyle. And they aren’t the only ones.

In fact, around 55% of dogs are currently considered overweight. But since Shih Tzu aren’t considered active dogs, this could lead to a particular propensity for weight gain over time (if their food intake and calories exceed what they burn). 

This means that the food you choose for them is important — you should purchase lower calorie and lower fat food that can help your Shih Tzu maintain their weight. Always checking, of course, to make sure that it also has enough vitamins and decent protein. 

I’ve compiled the best dog food for Shih Tzu, so you can choose the best option for your dog. 

While my personal pick is Whole Earth Farms Small Breed — as this is the food my dog has successfully lost weight on and maintained — I’ve also included reviews for nine other dog foods.

This dog food by Whole Earth Farms contains high-quality and fresh ingredients, such as salmon meal and chickpeas. With high levels of protein, but lower fat and calorie content, this food will satiate your Shih Tzu without overindulging them. 

This formula is cooked in America and made with fresh ingredients

The recipe includes apples, sweet potatoes, peas, and flaxseed for healthy fats, carbs, and protein, along with salmon and chicken meal. These ingredients also have fiber, which helps aid in digestion and can decrease gastrointestinal problems. 

This dog food also has added vitamins, minerals, and probiotics to support healthy digestion, and the brand states that their food can help reduce shedding and promote a shiny coat. 

The formula is free of wheat, grains, corn, soy, by-products, artificial colors, flavors, and preservatives.

As a Shih Tzu owner myself, this is my top choice for my beloved. I’ve exclusively fed him this dog food for more than half of his life, and have no plans to switch any time soon. They also have a wet food version that I feed him as a treat. 

Royal Canin Shih Tzu Puppy Dog Food

Royal Canin Shih Tzu Puppy
  • First 5 Ingredients: Brewers Rice, Chicken By-Product Meal, Corn, Chicken Fat, Wheat Gluten
  • Key Feature: Breed-specific formula exclusively for Shih Tzu puppies
  • Guaranteed Analysis: 26% Crude Protein, 16% Crude Fat, 3.6% Crude Fiber, 10% Moisture
  • Caloric Content: 355 kcal/cup
  • Type of Product: High Protein; Includes Grains; Breed Specific
  • Life Stage: Puppy 
  • Best for: Puppies

Shih Tzu are a toy breed, and so are extra small as puppies. Due to a smaller mouth, as well as potential health issues like kidney and heart problems, it’s important to feed a Shih Tzu puppy a well balanced and nutritious diet. 

The Royal Canin formula was specifically formulated for a Shih Tzu puppy that’s 8 weeks to 10 months old. Because of their small size, Shih Tzu puppies can be transitioned to adult dog food as early as 9 months — if you neuter them, maybe even earlier.

Every Shih Tzu is different, so talk to your veterinarian to see when your dog can make the switch. 

Because Shih Tzu have long hair with a dense undercoat, this formula is made with EPA, DHA, and vitamin A for both healthy skin and coat. Support your dog with this super oil blend. 

The recipe also includes ingredients like beets, antioxidants, and probiotics to promote a healthy stomach and eyes. 

This formula is smaller for kibble size, reducing choking hazards and giving Shih Tzu puppies the opportunity to chew their food without difficulty. 

This formula also includes grains, as well as corn and rice.

Wellness Complete Small Breed Senior Dog Food

Wellness Small Breed Complete Health Senior Deboned Turkey Peas
  • First 5 Ingredients: Deboned Turkey, Chicken Meal, Ground Brown Rice, Peas, Rice
  • Key Feature: Affordable dog food for senior Shih Tzu 
  • Guaranteed Analysis: 25% Crude Protein, 12% Crude Fat, 5% Crude Fiber, 10% Moisture
  • Caloric Content: 435 kcal/cup
  • Type of Product: No Corn, Wheat, or Soy; Weight Control
  • Life Stage: Adult 
  • Best for: Seniors

While this Wellness Complete dog food does have higher calories than others on our list, it is still a great option for senior Shih Tzu. Because many dogs eat less as they reach their later years, senior dog foods are usually higher in calories. 

However, the lower fat content in this recipe will keep your senior Shih Tzu from gaining extra weight. 

This formula is fortified with omega fatty acids, antioxidants, glucosamine, probiotics, and taurine

Taurine is a key amino acid that many dogs create themselves. However, the older dogs get, the bigger the chance they will be taurine deficient. With this dog food formula, you won’t have to worry about your dog losing out on proper nutrients. 

This food also includes pea fiber, tomatoes, and sweet potatoes to promote healthy bowel movements. And, due to its small kibble size, senior dogs can easily eat. 

This formula also includes grains like oatmeal, and both brown and white rice.

  • First 5 Ingredients: Chicken, Chicken By-Product Meal, Corn, Chicken Fat, Wheat

Have a Shih Tzu that’s more active or that needs to gain weight? Your best option will be  Eukanuba Small Breed Adult dog food. 

This formula is both high in protein (at 28%) and fat (at 18%), so it’s best for more active or underweight dogs that need to gain a few pounds.

It’s also higher in calories — which means measuring your dog’s food should be precise to avoid extreme weight gain. 

High energy dog food can also be used to help dogs with chronic diseases, like cancer, prevent weight loss. 

This recipe includes animal protein, glucosamine, and chondroitin sulfate to promote lean muscle development, with DHA and vitamin E to support healthy brain function and a healthy coat. 

Chicken is the first ingredient in this dog food, but it also includes wheat.

Guide to Buying Dog Food for Shih Tzu

When selecting nutritious and balanced dog food for your Shih Tzu, there are several important nutritional needs to look at. 

Nutrients Your Shih Tzu Needs

Eating a balanced diet is important for your Shih Tzu, as there are many common digestive and weight problems they can have. Because of these potential issues, it’s important to follow the proper dietary guidelines for dogs

Higher Protein  

Although Shih Tzu aren’t considered highly active, they do still need at least 21% crude protein. 

All of the dog foods on this list meet these requirements, and many are higher in protein than others. Because of their more sedentary lifestyle, too much protein can cause weight gain in Shih Tzu. 

In dog food, the best protein comes from meat as the first ingredient. After that, focus on other protein sources like pea protein, meat “meals” (like chicken meal or salmon meal), and higher protein vegetables and grains such as peas and chickpeas. 

Be sure that if you choose a food with more than 25% of protein you portion your Shih Tzu’s food correctly. 

Lower Fat 

While dogs require at least 8% crude fat, Shih Tzu need food right at, or just slightly higher, than the recommended amount. Due to their potential weight problems, high fat content can enable a Shih Tzu to gain weight quickly. 

While oils like canola oil or flaxseed oil can be great additions to dog food, be sure that they’re not the main ingredients. They should be lower on the list.

Another great option is fish oil. But, since Shih Tzu aren’t as active, they don’t need dog food with high crude fat levels.


Carbohydrates provide energy and are considered an important and essential part of your dog’s food. However, carbohydrates shouldn’t make up more than 20% of your canine’s diet. 

Try to avoid dog foods that include “simple” carbohydrates that will be hard on your dog, like white rice. 

Instead, focus on finding dog foods with carbohydrates like oatmeal, sweet potato, and brown rice. Because Shih Tzu can develop diabetes more easily, these complex carbs are preferable — they have a slower absorption rate, and so are less likely to cause hypoglycemia. 

These carbs will help keep your dog satiated and energetic, without the potential digestive issues.

Vitamins & Minerals

Vitamins and minerals are essential in your dog’s health functions, as well as in their growth. 

B-vitamins are important in aiding your Shih Tzu’s body in converting food into energy, creating new blood cells, and maintaining healthy skin; vitamins A and C support eye health and immunity; and minerals like iron help provide oxygen to cells. 

Most commercial dog foods, including the options on this list, already have the necessary vitamins and minerals that your dog needs in their daily diet.

How to Choose Food For Your Shih Tzu

After finding a food that meets your Shih Tzu’s dietary needs, it’s also important to look at a few other specific needs your furry friend may have. 

Your Shih Tzu’s Age 

While your Shih Tzu is growing, they will need more fat and protein. After weaning, a puppy will need around 23% of crude protein daily. This will slowly decrease over time, as they reach adulthood and their senior years.

Once they reach adulthood, their diet should consist of a balance of carbs, fat, and protein that supports adults. They’ll need around 21% crude protein, 8% crude fat, and 4% crude fiber, with carbohydrates being limited to 20% or less of their food source (according to the Association of American Feed Control Officials).

And, when they’re a senior, they may need more moisture, so wet food may be a better option. Senior dogs are more prone to dehydration, due to their bodies not functioning as well as they did when they were puppies. Providing water is a necessity, and wet food can help them with their water consumption. 

Kibble Size 

Because of their small size, Shih Tzu can choke on larger pieces of kibble. A large size could also cause tracheal collapse, although that’s the worst case scenario. 

However, it’s still better to be safe. Choose a food that has smaller, bite sized pieces that your Shih Tzu can enjoy. 

Caloric Needs

As an adult, a Shih tzu will need about 35 calories of food per pound of weight they have. 

As an example, if your Shih Tzu is the average size of about 10 pounds, they will need 350 calories a day to sustain their energy levels — which you can split into two or three meals. 

My Shih Tzu has epilepsy, and, due to his medication, he’s required to eat slightly fewer calories than the average Shih Tzu. If your dog has any medical conditions, extreme allergies, or is super active, talk to your veterinarian to figure out their caloric needs.

Common Shih Tzu Health Issues 

Nutrition and the food you choose for your Shih Tzu can impact their health. Here are the most common health issues amongst this breed that diet can help manage. 


Common amongst Shih Tzu, hypothyroidism is when their thyroid gland doesn’t produce adequate amounts of the thyroid hormone. Because of this, there is usually inflammation.

Due to hypothyroidism, excessive weight gain, ear infections, and lethargy are common. Managing your Shih Tzu’s food source and feeding them proper portions can help manage this condition with or without medication. 

If they are still gaining weight, even with proper food portions, take them to your veterinarian to check their hormone levels. 


One of the most common health issues with Shih Tzu is their susceptibility to becoming overweight or obese. 

The average weight for a Shih Tzu shouldn’t exceed 16 pounds. 

Using a weight control dog food, measuring the proper serving size, and feeding smaller portions more often can help your Shih Tzu avoid weight gain. 

Tracheal Collapse

Tracheal collapse happens when there is an airway obstruction in dogs. This is common amongst many toy and small breeds, including Shih Tzu. 

While the exact cause for tracheal collapse is unknown, eating food that isn’t the right size can trigger symptoms. This is why it’s important to find food specifically for small and toy breeds. 

The cause of tracheal collapse is unclear, but symptoms can be provoked by eating the wrong size food. In obese dogs, these symptoms and problems can be worse. 

FAQ About Shih Tzu Dog Food

Have any questions about your Shih Tzu? Here are some answers to questions you may have. 

Can Shih Tzu puppies eat adult dog food?

Shih Tzu puppies should eat puppy food until they’re at least 7 months old, with the recommended age at 9 months or older. 

Adult kibble can cause a choking hazard. Plus, adult food is usually lower in the fat content and nutrients that puppies need to grow. 

How often should I feed my Shih Tzu? 

Just like an adult human, a Shih Tzu does best with a more regular eating schedule. 2–3 feedings a day should be sufficient. 

Just remember that all feedings should be equal to or less than the max feeding guidelines on the dog food you purchase. 

What should I do if my Shih Tzu is a picky eater?

If your Shih Tzu is picky or becomes picky, choosing a wet food or mixing wet food in with their regular kibble can help. 

This may depend on your budget and their dietary needs, but feeding them wet food can keep them from refusing food. 

Can Shih Tzu eat grain-free diets?

Most Shih Tzu can thrive on a diet with grains and carbohydrates. But, if they have allergies, or if your veterinarian recommends a grain-free diet, follow those recommendations. 

Can my Shih Tzu eat human food?

Of course, as long as it isn’t considered toxic to dogs. Also consider making dehydrated treats, like sweet potato, for your Shih Tzu to enjoy longer. 

Our Verdict

Just like all other dogs, Shih Tzu need a balanced diet with the vitamins and minerals that support their health. If their needs aren’t met, they can be subject to health issues and disorders, as well as lethargy. 

Whole Earth Farms Small Breed dog food is my personal favorite choice for my sweet and cuddly pup, and is the best dog food for most Shih Tzu. 

It is high in protein and lower in calories, which will help your Shih Tzu avoid weight gain without sacrificing muscle. Plus, it’s easy to find both in dry and wet food options, in multiple flavors (for picky Shih Tzus), and is made with simple ingredients.
