Nutritional Breakdown
On a dry matter basis (10% moisture), the formula provides approximately 25% protein, 16.7% fat, and 4.4% fibre. The protein level is lower than Purina Pro Plan (29.5% DM) but still meets AAFCO requirements for adult maintenance. The higher fibre content (4% vs 3%) is beneficial for stool consistency, which many owners of sensitive stomach dogs prioritise.
Chicken is the first ingredient, which makes this formula unsuitable for dogs with chicken sensitivity. The carbohydrate base uses whole grain wheat, barley, and sorghum, providing a mix of soluble and insoluble fibres. Dried beet pulp is an excellent prebiotic fibre source that feeds beneficial gut bacteria.
Notably, this formula does not include added probiotics. While the prebiotic fibre supports existing gut bacteria, dogs that benefit from live probiotic cultures would need a separate supplement or should consider Purina Pro Plan instead.
