Is It Okay to Include Grains Like Rice in Your Dog's Diet? A Scientific Look at Urban Dog Nutrition

🍽️ Estimated Protein Content of 30% Chicken (As Fed and DMB)

Assuming skinless raw chicken has ~22% protein as fed:

  • 30g chicken (in a 100g total recipe) β†’ 30g x 22% = 6.6g crude protein
  • If food is ~70% moisture, Dry Matter = 30g
  • Protein on DMB = (6.6g / 30g) x 100 = 22% DMB

This fits neatly into a kidney-friendly range for adult, city-living dogs.


πŸ₯£ So What Should You Do?

If your goal is to create a general-purpose, safe-for-most adult dogs formula, especially for urban or indoor dogs, then:

  • βœ… Consider adding rice or veggies to lower protein
  • βœ… Reduce phosphorus and kidney load
  • βœ… Provide clean, digestible energy
  • βœ… Balance satiety and GI health
  • βœ… Cut formulation costs without compromising health

This approach still meets or exceeds AAFCO guidelines for adult maintenance.

🍚 Will 25% Cooked White Rice Spike Blood Sugar?

Short answer: Not significantly, when used in a complete and balanced meal.

  • White rice has a high GI (70–90), but glycemic load is moderated by fiber, fat, and protein.
  • At 25% inclusion, the rice still contributes useful energy without overwhelming the glucose regulation system in most healthy dogs.
  • For urban, adult dogs, this is unlikely to cause problems if paired with lean meat and fiber-rich veggies.

βš–οΈ Risk/Benefit Analysis at 25% Rice:

Potential Benefits:

  • Clean, digestible energy
  • Improved satiety and GI regularity
  • Cost-effective
  • Protein dilution for kidney support

Potential Risks (when unchecked):

  • May not be suitable for diabetic dogs
  • Can increase glycemic load in overweight dogs
  • Slight reduction in overall protein and micronutrient density

Overall: βœ… Still acceptable for general maintenance diets, especially for city and early senior dogs.

πŸ”¬ Scientific & Industry References

  • Studies show cooked rice is >95% digestible by dogs
  • Dogs evolved more AMY2B genes for starch digestion
  • Whole grains help gut health via resistant starch and fiber
  • FDA's DCM review pointed at legumes, not grains, as a risk

Key Journals & Findings:

  • Dogs tolerate grains better than legumes in many studies
  • No evidence that grains alone cause allergies or obesity


πŸ”‘ Origin & Rise of Grain-Free Dog Diets

  • Emerged after 2007 pet food recalls
  • Pet food brands marketed "grain-free" as superior and safer
  • Tied to human clean eating and paleo trends
  • Fueled by fear-based marketing, not medical necessity
  • Studies show no benefits of grain-free for most dogs

πŸ” Conclusion: Including Grains Is Perfectly Okay

Grains like white rice (15–30%) can be a smart part of a balanced dog diet:

  • βœ… Help reduce protein/phosphorus load
  • βœ… Easy to digest
  • βœ… Safe for urban, adult, and early-senior dogs
  • βœ… Meet AAFCO nutrition standards

Dogs are not wolves. They have evolved to digest starch, and unless your dog has a specific diagnosis, there's no need to avoid grains. In fact, a 30:45:25 meat-veggie-rice split is often ideal for city dogs.

At Momo&Co, we use grains thoughtfully, not fearfully. Because good food isn’t about trends. It’s about balance.
