The 6 Best Dog Foods For Shih Tzus With Allergies

Finding the appropriate food for your Shih Tzu can be difficult, but if your dog has allergies, it can be even more difficult. A food allergy in a dog implies that their immune system is stimulated and overreacts to a specific element in the food, resulting in an allergic response.

Antibodies are made to fight this threat, and your dog may have skin inflammation or itching, hot spots, itchy paws, diarrhea, or even throw up.

Some food allergies can be managed by changing a person's diet so they don't eat the foods that cause their allergic reactions. Always consult your veterinarian to choose the best food for your dog.

To help you decide which foods to try, BestForPets (bestforpets.org) has compiled a list of the best dog foods for Shih Tzus with allergies.You may read the reviews of each meal and choose which one is best for your dog.

Buyer's Guide: How to Choose the Best Dog Food for Allergy-Prone Shih Tzus

Shih Tzus, like people, can be allergic to a variety of substances. Shampoos, pollen, and food additives, to mention a few, can all cause allergic responses. Food allergies develop when your dog’s immune system sees an eaten item as an invader and seeks to protect him from it.

The following are the most common food allergy symptoms:

  • Itching
  • Skin that is red, flaky, or irritated
  • Loss of hair
  • Infections of the skin
  • licking or chewing on the skin and paws
  • Vomiting
  • Lethargy
  • Diarrhea or constipation
  • Hyperactivity
  • Aggression
  • Coughing or sneezing
  • Infections of the ears

Food allergies can make life difficult for your Shih Tzu. It is critical to locate the correct cuisine for them in order to reduce these symptoms.

Always with your veterinarian before switching your dog’s diet. Your veterinarian is the finest source of information on what foods are safe for your dog to consume.

Here are a few things to consider while selecting dog food for allergic Shih Tzus.

Dog Food with Few Ingredients

The fewer components in the dish, the less likely something in the food may cause an allergic response. Limited-ingredient dog diets contain brief ingredient lists that are frequently full of easily recognized substances. You can simply avoid an ingredient if you know what your dog is allergic to (this may be established by your vet through meticulous testing and food trials).

Food for Hypoallergenic Dogs

Hypoallergenic dog diets were developed particularly for dogs that cannot consume ordinary food due to allergies. These diets, which normally require a prescription, supply your dog with the nourishment they require while being extremely cautious to avoid any potential allergies. However, this meal is not always as tasty as conventional cuisine. Prescription food may not interest your Shih Tzu in the same way as prior meals did.

Stage of Life

Make sure to get dog food that is appropriate for your dog’s age. Sometimes a meal is created for all ages, and as long as this is stated directly on the label, you can feed it to your dog. Puppies, adult dogs, and elderly dogs, on the other hand, require various nutrients. The diet for each life cycle will be balanced and tailored to the age of the dog.


Protein is the most crucial component of your dog’s diet. The food’s protein content should be higher than its fat level. Unfortunately, protein is the most prevalent element to which dogs are allergic.

Dogs can acquire allergies at any age, so it’s conceivable that your dog ate chicken for years before becoming sensitive to it. If your dog is allergic to the protein in their diet, the simplest solution is to switch the protein source. A novel protein that your dog hasn’t had before is typically advised.

The risk of allergic responses increases when the food contains more than one protein source.
