Special Food Considerations for Shih Tzus

Most shih tzus are healthy, but the breed is prone to the following health conditions: hip dysplasia, patellar luxation (a slipped kneecap), eye anomalies including cataracts, progressive retinal atrophy, retinal detachment, other eye issues.

Maintaining a healthy weight can reduce the risk of hip and knee problems. Studies indicate that vitamins A, C, and D can keep a dog’s eyes healthy, so your pet’s food should include these nutrients. Finally, omega-6 fatty acids can keep your Shih Tzu’s skin and hair healthy.

Choosing the Best Dog Food for Shih Tzus: What to Look For

There are three factors you need to consider when choosing the best dog food for your shih tzus: price, quality, and type (dry or wet). Here is how to consider the best dog food across each of these factors:

Price

Inexpensive dog food generally includes ingredients that you don’t want to feed to your shih tzu such as poultry by-product meals, corn, wheat, soy, artificial flavors, and preservatives. These ingredients have negligible nutritional value and may even be detrimental to your dog’s health.

Quality

High-quality dog foods include meat as their first ingredient. They also list vegetables, fruits, vitamins, and minerals that will enhance your pet’s health. It should also includ include omega-3 fatty acids, omega-6 fatty acids, and biotin to encourage the growth of your shih tzu’s long, silky, hair.

Type

The dog food discussed in this review is available in dry (kibble) and wet (canned) recipes.

The Best Dog Food for Shih Tzus: Reviewed and Ranked FAQs (Frequently Asked Questions) 

What amount of dry dog food should I feed my canine?

Most dog food companies include a chart on each bag of dry dog food. Oftentimes, the weight of a dog is what dictates how much dry food it needs. So, it’s best to go by the weight chart on the back of a dry dog food bag to ensure you’re giving your dog the proper amount of nourishment.

Can I mix a combination of dry and wet dog food together?

Yes, wet and dry dog food can be mixed together. Many owners mix a little wet food in with dry food to make the food more appealing and tastier for their dogs. However, keep in mind that when mixing foods, it is important to make sure both the wet and dry foods are designed to match the dietary needs of your dog. For example, this means that you should avoid mixing dry puppy food with wet adult food.

Does dry food contain more protein than wet food?

No, most dry foods have a lower protein content than wet foods. Wet foods are often formulated with premium meat, poultry, or fish ingredients as the first ingredient.
