Detailed Recipe Analysis: Diamond Maintenance
We analyzed Diamond Maintenance as a representative formula. Key ingredients: chicken by-product meal (protein concentrate from organs/feet), wheat flour, ground corn, rice bran, beet pulp, chicken fat, sorghum, ground white rice, fish meal, egg product, flaxseed.
Diamond Care Sensitive Stomach
Estimated Dry Matter Nutrients:
- Protein: 24.4%
- Fat: 13.3%
- Carbs: 54.3%
Fiber: 3.5%. Pros include chelated minerals (e.g., zinc proteinate) for absorption and probiotics (Lactobacillus, Bifidobacterium) for gut health. Concerns: grains like wheat/corn (modest nutrition), sodium selenite (less ideal selenium form). Overall, meat-forward with 65% fat-to-protein ratio—above average vs. typical kibble.
By-products boost protein efficiently (300% more than fresh chicken), and flaxseed adds omega-3s. Beet pulp aids digestion despite filler debates.
Nutrient Profile Strengths
Brand averages: 29% protein, 19% fat, 44% carbs. This meat-notable profile suits most dogs, per AAFCO standards. Probiotics and omegas enhance skin/coat, drawing from veterinary nutrition expertise like Laura Ward’s (BSc Animal Science).
