Quick answer
After evaluating dozens of options, we recommend Royal Canin Shih Tzu Adult Dry Dog Food as the best overall low fat dog food for Shih Tzus. It is breed-specific with controlled fat and calories to support weight management.

What to consider for Low Fat Dog Food For Shih Tzus
Shih Tzus are prone to obesity and pancreatitis due to their small size and genetic predisposition. A low fat diet helps maintain a healthy weight and reduces the risk of digestive upset. Look for a formula with moderate protein (around 25 to 30% dry matter) and fat content below 12% to support energy without excess calories. Also consider kibble size and texture, as Shih Tzus have small mouths and may struggle with large pieces. Joint support and omega fatty acids are beneficial for their long-term health.
What to look for in a dog food
When choosing a low fat dog food for your Shih Tzu, ensure it is AAFCO complete and balanced for the appropriate life stage (adult or all life stages). The first ingredient should be a named meat source like chicken or salmon. Look for moderate protein (25 to 30% dry matter) and low fat (8 to 12% dry matter) with calorie density around 300 to 350 kcal per cup. Small breed formulas are ideal because of kibble size. Added glucosamine and chondroitin support joints, while omega-3 and omega-6 fatty acids promote skin and coat health.
How we chose these picks
- Analyzed ingredient lists for named protein sources and low fat content
- Checked AAFCO nutritional adequacy statements
- Reviewed calorie density and portion recommendations
- Considered breed-specific and small breed formulations
- Evaluated customer feedback for palatability and digestive tolerance
- Prioritized brands with strong safety and quality control records
- Compared price per pound to ensure value
- Never ranked a product higher just because it pays a commission
What to avoid
- Avoid foods with unnamed “meat meal” as the only protein source
- Be cautious with grain-free or legume-heavy recipes due to the FDA DCM investigation; grain-inclusive is often safer unless your vet advises otherwise
- Do not use all-life-stages food for a Shih Tzu puppy unless it meets large breed puppy guidelines (not typically needed)
- Always transition to a new food gradually over 7 to 10 days to avoid digestive upset
