Digestibility

Value Analysis
Rachael Ray offers grain-free at $1.50/lb. Taste of the Wild delivers premium quality at $1.93/lb. ORIJEN commands $3.80/lb but justifies it with quality. Choose based on budget and dog's needs.
Taste of the Wild High Prairie
Why We Chose It
Delivers premium grain-free nutrition at a mid-range price. The buffalo and venison proteins, combined with proprietary probiotics, offer excellent nutrition without the ultra-premium cost of ORIJEN.
Taste of the Wild High Prairie wins for offering premium grain-free nutrition at a reasonable price point. The novel proteins work well for sensitive dogs, and the probiotics support digestion. ORIJEN is worth the premium for dogs with serious issues. Rachael Ray offers entry-level grain-free for budget-conscious owners.
Final Thoughts
