Buying Guide for Shih Tzu Dog Food

When it comes to buying the best food for shih tzus, the first important thing to understand is that there is no “one size fits all” design. Given this fact, there are several important aspects to consider to ensure your dog gets the right dose of nutrients for great digestibility, and longevity.

Common Shih Tzu Health Issues

Shih tzus are healthy dogs for the most part, but do suffer from certain problems common to small breeds.


This is basically inflammation of the cornea, which can gradually lead to an ulcer, and cause blindness if the condition is severe enough. Apart from getting your dog looked at by your vet, there are several nutritional supplements that may help ease the discomfort such as omega-3 fatty acids, and vitamins C and E.

What is the Best Dog Food for Shih Tzus with Allergies?

Shi tzus can be affected by allergies, which are quite similar to those that affect the human anatomy. Even though most of these allergies are food based, and can be resolved by trial and error, there are some shih tzus who can be allergic to certain products such as shampoos and flea powders.

There are several symptoms of allergies in shih tzus to watch out for including itchy ears, vomiting, diarrhea, hives, inflamed skin, sneezing and itchiness. You can give your dog several different medications to treat his allergies after speaking with your vet of course.

Food containing antioxidants are recommended for allergies, and can help protect the body from damage caused by free radicals.


Also known as underactive thyroid, hypothyroidism happens when the thyroid gland doesn’t make enough thyroid hormones. Even though this condition is not common to smaller dogs, there are some shit tzu owners who claim otherwise. Symptoms of Hypothyroidism include an abnormal appetite, hair loss, fatigue, and weight gain.

Foods alone won’t cure hypothyroidism, but can treat the symptoms resulting from the condition such as weight gain. If your dog tips the scales at a larger number compared to its size, then look for dog food that’s low in calories, and visit your vet to seek medical advice.

What to Look for in Shih Tzu Dog Food?

Proteins – arguably the first thing to look for in shih tzu dog food, proteins contain essential amino acids to help your dog function properly. Proteins also contribute to healthy hair and skin, tissue repair, and muscle development among other benefits.

In terms of dosage, the amount of protein required depends on the age and level of activity of your dog, but between 22 percent and 25 percent is recommended for adult shih tzus.

Vitamins – just like humans, shih tzus need a good intake of vitamins too. The best dog food for shih tzus should be infused with vitamins, most notably vitamins A, B, C, D, E, and K.

Kibble size – this is perhaps one of the most important aspects to consider, so pay attention. Shih tzus are flat-faced dogs, hence will find it harder to eat large size kibble. Feeding large kibble to your shih tzu can also result in ingestion, and lead to cuts in his mouth. The solution is simple – buy shih tzu dry dog food that’s small in size.

Supplements – these include omega-3 and omega-6 fatty acids, which can curb your dog’s allergies. Other supplements such as chondroitin and glucosamine can improve bone health, and provide antioxidants for a healthy nervous system.

Final Thoughts

Even though the origin of shih tzus is still a mystery, one thing’s for sure – they are loyal, gentle and affectionate, and require minimal exercise. Shih tzus can also suffer from several health conditions, but feeding your dog a well-rounded diet will keep them healthy, build his immune system, and improve his overall health.
