If you’ve raised a Shih Tzu before, then you surely know that this dog breed can be one of the sweetest and most energetic companion dogs. They’re also famous for their beautiful locks and coats. However, Shih Tzus are genetically prone to skin allergies and may be sensitive to some types or brands of dog food.

The best dog food for a Shih Tzu with allergies is Nature’s Recipe Grain-Free because it is highly rated in terms of selective yet nutritionally balanced ingredients, consumer reviews, and value for money. Its formula is specially designed for dogs with allergies.

As you read on, you will find out more about the factors to consider when choosing dog food for a Shih Tzu with allergies and the benefits of feeding such a pet with Nature’s Recipe. I will also discuss other dog food brands and homemade alternatives that can help minimize your pet’s allergy symptoms.

Factors To Consider When Choosing a Dog Food for Shih Tzu With Allergies

Although most allergies among Shih Tzus are not related to food, selecting the right kind of food for your pet matters a lot. That’s because once the dog has started exhibiting allergic reactions, their immune system may become unstable and recognize other possible allergens as threats. As a result, their condition can get worse if they are not fed the right kind of food.

Since there are many dog food brands on the market, with all of them promoting their product’s edge over the others, it may not be easy to find the one that best suits your dog.

Often, finding the right dog food requires a lot of trial and error. This can be complicated as dogs need time to adjust to new food. You have to transition your dog’s diet slowly to avoid further stomach and digestive problems.

Here are some things you should consider when choosing dog food for your Shih Tzu with allergies:

  • Ingredients
  • Customer reviews
  • Value for money

Winners: Nature’s Recipe and Merrick

A Shih Tzu’s allergies can be related or unrelated to food. If you haven’t taken your dog to the vet for a thorough medical examination to confirm what they are allergic to, it’s best to find a dog food product that poses the least risk of further allergic reactions.

Below are some reasons why Nature’s Recipe and Merrick are the best in terms of ingredients:


Many people tend to feed their dogs with grain-free products when they notice allergy symptoms. While this may be the best place to start, it is important to understand that dogs also need grains for energy.

Most grains provide dogs with the following:

  • Carbohydrates
  • Fiber
  • Vitamins
  • Healthy fats
  • Proteins

However, although rare, some dogs may indeed be allergic to grains like wheat, rice, corn, and barley. That is why your vet may initially advise you to introduce a grain-free diet to your dog and see if there are any improvements.

Both Nature’s Recipe and Merrick use alternative sources of carbohydrates, such as sweet potatoes, pumpkin, and potatoes. Most dogs allergic to grains do not show adverse reactions to these other ingredients, making these two products the best options to start feeding your dog.

However, a Shih Tzu with severe allergies is highly susceptible to a secondary yeast infection. This infection is a result of your dog’s weakened immune system. It can lead to more skin irritation and discomfort in your dog.

Regardless of the food source, yeast feeds on sugar or carbohydrates. A high-carbohydrate diet for a dog with a compromised immune system may result in yeast infection that can be pretty challenging to manage.

Luckily, once you address your pet’s allergies, their immune system will get well enough to control the yeast overgrowth on their skin, which will make the yeast infection go away.

Protein Source

Another good point about the ingredients of Nature’s Recipe and Merrick is that they use salmon as the primary protein source. A Shih Tzu with food allergies is often sensitive to proteins found in beef, chicken, or eggs.

Salmon, on the other hand, does not contain such allergen. It also contains healthy nutrients, such as omega-3 fatty acids, that can help boost the immune system, making it the best protein source for your dog with allergies.

The bottom line: Nature’s Recipe and Merrick may not be the best dog food products on the market, but they are the best place to start if you take care of a Shih Tzu with food allergies. Both brands take dog allergies into consideration when developing the food formula, thus avoiding common allergens. Their formula also ensures that your pet will be getting all the necessary nutrients of a well-balanced diet.

Winner: Hill’s Science

Although there are plenty of perfectly healthy Shih Tzus, it is important to understand that allergies are also pretty common among this breed. You may not notice it immediately after you adopt a puppy as the symptoms usually set in after the puppy turns one year old.

In most cases, female dogs with allergies produce only one or two puppies in the litter that will eventually exhibit allergy symptoms, while the others avoid being prone to allergies. Nevertheless, if your Shih Tzu with allergies is pregnant, understand that some puppies will highly likely have the condition too.

At the same time, if the Shih Tzu you got from a breeder starts exhibiting allergy symptoms a year after you got them, chances are their parents or siblings may also have the same symptoms. You may reach out to your breeder to ask for suggestions on how to treat your puppy’s allergies.

The breeder may advise you of dog food brands and management strategies that they have tested and proven effective for their older dogs.

If you and the breeder are at a loss for the best dog food for your immunocompromised pets, you can consult other consumers online. To help you with that, this article has rounded up some of the best-reviewed products that you can see online.

Homemade Alternatives to Dog Food for Shih Tzu With Allergies

While commercially available dog foods are pretty convenient and widely available, some pet owners still struggle to look for the product that best suits their pets. Fortunately, there are many safe, homemade recipes that you can feed your Shih Tzu even if they have allergies.

Shih Tzus are generally not picky-eaters and would chow down on any meal, treat, or snack. However, some may exhibit a picky behavior, and if your dog is one of those, you may want to use several recipes on a schedule, so they don’t get bored with having the same dish over and over again.

The Advantage of Making Homemade Dog Food

One significant advantage of making homemade dog food for your Shih Tzu with allergies is that you don’t have to spend much money on a bag of dog food that will otherwise go to waste if it turns out ineffective or sometimes even harmful for your dog. 

Keep in mind the ingredients you need to avoid when making homemade dog food to ensure that your dog will be safe. When you find safe ingredients for your dog, you may slowly transition them to commercially available dog food containing similar ingredients.

The Disadvantage of Making Homemade Dog Food

The downside to preparing homemade food for your dogs is that it takes a lot of time and effort, and you may need to prepare several servings in advance. However, if you have the time and the passion for cooking, it can also be a fun experience for you and your pet.

Factors That Trigger a Shih Tzu’s Allergies

Shih Tzus resemble a ball of happiness as they approach their humans with affection and energy. While they tend to be sweet to their humans, they can also be very feisty when displeased.

They are rich in various emotions and can express themselves well, making them an interesting companion dog breed. However, once they start showing discomfort by obsessively scratching or licking their skin, it can be distressing to you and your Shih Tzu.

Some pet owners who’ve had Shih Tzus before understand that the breed requires a lot of work, and they need regular grooming to keep their coats healthy and untangled. Skin allergies are common amongst Shih Tzus, so regular grooming can help you catch any irritations before they become a bigger problem. 

Here are some things that can trigger a Shih Tzu’s allergies:

  • Pollen
  • Dust
  • Fleas, ticks, or mites
  • Smoke
  • Grains (like wheat)
  • Specific proteins (like those found in eggs, chicken, and beef)
  • Dairy products (like milk or cheese)

Several other dog food ingredients can also trigger allergic reactions or worsen the symptoms of Shih Tzus with allergies. Regardless of the cause, they all result in extreme discomfort, itchiness, and sometimes even pain to your dog.

Here are some allergy symptoms your Shih Tzu may exhibit:

  • Licking the paws
  • Rubbing the face
  • Rashes or scabs on the feet, belly, and skin folds
  • Smelly ears
  • Obsessive scratching behind the ears
  • Diarrhea
  • Vomiting
  • Runny nose
  • Teary eyes

You may also notice your dog looking uneasy or whimpering in pain. All these symptoms can be disturbing to any pet owner, but luckily, they are manageable. The main challenge is how to determine what your pet is allergic to. 

A vet visit and lab tests can be costly, so pet owners often employ trial and error to find the most suitable conditions to help alleviate their pet’s symptoms. Moreover, it is pretty important to find the best dog food that is safe for your Shih Tzu with allergies, as it can make a world of difference.


Finding out that your precious Shih Tzu has allergies can be stressful for you and your pet. Luckily, the condition is manageable and often boils down to choosing the right kind of dog food. 

There are many readily available products to choose from on the market, including Nature’s Recipe Grain-Free. If it doesn’t work for your dog, you can always try the other excellent options presented in this article or try making a homemade recipe.
