What Are The Types Of Shih Tzu Allergies?

Twenty percent of canines are oversensitive to at least one sort of sensitization.

Besides, you cannot instantly figure out if your dog has hypersensitivity.

Most likely, he would be fed or exposed to the allergen before you can decide he is allergic to a material or ingredient.

So, if you own a Shih Tzu, you should be aware of all types of allergies they are disposed to.

Flea Allergies

These allergies are caused by fleabites and are known as flea allergy dermatitis.

Dogs are allergic to flea saliva, but some are not bothered by it. They only experience just an insignificant irritation.

Many hounds develop sensitization to the bite of just one flea and experience excessive itching.

They scratch and bite until the skin is criticized and the hair is sporadic.

If your canine has red bumps and skin rashes, suspect a flea allergy.

It is necessary to remove fleas before treating this allergy.

It is somewhat difficult to eliminate fleas from the environment completely.

Therefore, we recommend using modern flea medications because they are much more effective than collars, shampoos, etc.

The cherry on the top is that they require just one application in the whole month.

Food Allergies

Many pet food companies use additives in their foods that are the biggest cause of food allergies in dogs.

Mostly, low-quality foods contain additives and fillers.

Nonetheless, some leading brands also put synthetic and chemical preservatives, colors, and flavors in their recipes.

Some mongrels are sensitive to gluten and grain-inclusive foods, so you should avoid feeding them formulas that have grains or gluten.

Occasionally, some Shih Tzus are sensitized to animal or plant-based protein. In such a situation, you should serve them a vegan diet.  

Contact Allergies

These allergies are triggered by something your baby directly interacts with, such as plastics, carpet, grooming products, perfumes, cigarette smoke, feather, dander, shampoos, conditioners, etc. 

House cleaners or other types of chemicals can also cause these allergies.

The allergy signs appear on the body part that comes into contact with the allergen so that you can anticipate witnessing signs in their paws, feet, abdomen, etc.

These allergies result in hair loss, excessive scratching, red, itchy skin, etc.

Contact allergies are uncommon in Shih Tzus, but if your dog has a contact allergy, you will have to join up with your veterinarian to discover the allergen and eradicate it from his surroundings.

Environmental Allergies

Airborne allergens such as grass, weeds, pollens, etc., are the root cause of these allergies.

Aerosol spray and air fresheners can also instigate them.

If your cutie pie has an environmental allergy, always keep your house clean and inhibit him from going outside.

Restricting his exposure to outdoors can help in preventing any sensitivity response.

Why Does Shih Tzu Develop Allergies?

Particular ingredients in their food initiate their allergies, such as proteins, grains, or byproducts.

Many people feed grain-free diets to their hounds to prevent grains-related allergies.

However, they are unaware that 100% grain-free foods have a destructive impact on their heart, especially on miniature canines.

Therefore, before feeding grain-free food to them, consult with the vet.

Just like humans, each mongrel is different and thus will have diverse requirements.

What’s good for your friend’s dog may not be suitable for yours. So, you must know your options.

At times, consuming the same diet for many years can actually trigger an allergic response.

This may sound weird, but there is a straightforward clarification to it: Shih Tzus develop hypersensitivity to certain ingredients over time because they consume the same thing regularly; their body becomes less capable of breaking down those ingredients.

When this occurs, their body begins to categorize the ingredient as dangerous and consequently generates antibodies to combat the troubling food.

This process causes the signs we recognize as sensitizations.

If your dog has sensitivities or a delicate stomach, a simple modification in his daily diet can solve the problem.

However, before switching his diet, confirm he has allergies.

How To Figure Out A Shih Tzu Has Allergies?

If you are doubtful if your doggie has sensitivities, look out for these symptoms:

  • Hot spots
  • Bald patches
  • Paw licking at the tail’s base
  • Extreme itch
  • Excessive licking
  • Face swelling
  • Skin inflammation
  • Red, itchy eyes
  • Chewing or scratching on different body parts
  • Vomiting
  • Diarrhea
  • Anaphylaxis
  • Frequent wheezing or sneezing

If your precious buddy is hypersensitive to a certain ingredient, he may or may not develop diarrhea, loose stools, or vomiting, but it is not always true.

In fact, if he vomits or develops diarrhea after consuming a certain formulation, it is a clear sign that he has food intolerance instead of a food allergy.  

Food allergies exhibit themselves as diverse skin problems, but the right approach to pinpoint them is with proper testing by a vet.

If you are sure, your little one has a food allergy, consult with the vet. He will help differentiate between if he has food intolerance or allergy.

The immune system causes food sensitivity, whereas food intolerance originates from a stomach problem.

Suppose the vet confirms that your baby is allergic to his food. In that case, the possible starting point will be a transition in food and trying to eliminate offending ingredients such as synthetic additives, preservatives, certain proteins, and grains.

If diet modification is necessary, it is compulsory to make the shift gradually to prevent any potential problems.

On the flip side, if he has a food intolerance, it will also require a transformation in his daily diet.

Either way, before choosing the best dog food for Shih Tzu with allergies, discover the problem.  

Which Methods Do Vets Use To Identify Allergies?

Radioallergosorbent Testing

This blood test is utilized in humans and pets for pinpointing allergies.

It scans for antigen-induced antibodies in Shih Tzu’s blood.

It tests the blood for a reaction to molds, dirt, pollen, etc., as well as certain ingredients and contact allergies.

Regrettably, there are several fictitious positives with radioallergosorbent testing. So, it is not 100% reliable.

Elisa Blood Testing

This enzyme-linked immunosorbent assay is identical to the radioallergosorbent testing.

The vet injects a small amount of antigen into the dog’s skin and then observes that area for the symptoms of a reaction.

These tests give accurate results in humans but not in pets.

Intradermal Allergy Test

In this type of test, the vet shaves a patch of fur and injects a small number of potential allergens beneath the skin’s surface.

After 20 minutes, he examines the area for the signs of reaction.

Keep His Allergies In Mind

As we mentioned above, these beautiful babies are prone to sensitive stomachs and allergies.

That’s why; if your furry friend has allergies, ensure to recite the ingredients written on the food packaging before buying it.

The majority of dogs are allergic to chicken, beef, or grains, so look for foods that don’t contain these components.

Well-Balanced Nutrition

These handsome hounds require a nutritionally balanced diet that flaunts healthy fats and proteins with complex carbs to provide fiber.

Legitimately, to get the label of whole and nutritionally balanced, it must meet the minimum or maximum levels of fats, protein, vitamins, and minerals defined by AAFCO.

Remember, the particular levels of these nutrients vary based on the canine’s life stage.


Like other mongrels, Shih Tzus also need a higher protein content in their daily diet to develop and maintain strong muscles.

Ensure the food you have selected is made with reliable protein sources such as fish, beef, eggs, etc.

Inactive mutts require 30% protein, and highly active doggies need 35% protein regularly.  

Vitamins And Minerals

If your four-legged buddy has had a sensitivity reaction, we bet that his skin is feeling itchy and extremely uncomfortable.

Vitamins and minerals in the best dog food for Shih Tzu with allergies can aid his skin heal and feel comfortable rapidly.

Thus, you should buy food that features minerals and vitamins obtained from fruits and vegetables.

Synthetic vitamins and minerals are tremendously harmful to a dog that has had an allergic reaction.


You should purchase food with high protein and fewer carbs.

Shih Tzus don’t need a carbohydrates-dense diet since they are prone to obesity.

Choose a recipe with less than 25% carbs.


This dog breed has dense fur, so they require a diet with a low amount of fat.

The fats help keep their fur lustrous and healthy.

They need a minimum of 20% fat regularly in their food.

High content of fat will lead to weight gain.  

Easy Digestion

We recommend you select healthy food for Shih Tzu that is easy to digest and gentle on their fragile tummies.

If he frequently suffers from diarrhea or vomiting, look for food with low content of protein.

However, a fiber-rich diet can improve their digestion.    

Small-Sized Kibble

These tiny pups with tiny mouths and jaws should be fed small-sized kibble so that they can easily chew and swallow without obstruction.

Also, they are perceived as picky eaters, so if they don’t like their food, they won’t eat it.


As they are predisposed to allergies which can trigger skin rashes, leaving a rough texture.

Therefore, look for food with supplements like omega 3 and 6 fatty acids to prevent these allergies.

They also need many other supplements such as chondroitin and glucosamine for joint and bone health and antioxidants for strong immunity.

Type Of Food to avoid allergies

There are two types of foods that you can feed to avoid allergies.

Hypoallergenic Food

They are specifically formulated for canines that cannot consume regular food available in the market.

They help prevent them from having a negative reaction to the ingredients in the diet.

Hypoallergenic diets are made with less-common protein sources, so the dog’s antibodies don’t recognize them as antigens.

It means they can consume food without experiencing any allergic reaction.

The disadvantage of these diets is that some individuals have interrogated their validity.

Limited Ingredient Diet

These diets are the best for these tiny doggies because they are made with as few ingredients as possible.

It means there are negligible chances of them suffering from an allergic reaction.

You should use them to determine what component was actually making them itch or scratch their body.

The only downside of them is that they might not include as many minerals and vitamins as other recipes with a long list of ingredients.

Furthermore, it is not confirmed that they will stop them from having allergies if one of the limited ingredients still distress them.

However, they definitely aid you in figuring out ingredients your fur baby is sensitized to.
