This beef formula solves the #1 limitation of standard Pro Plan - chicken sensitivity. With beef meal as the sole animal protein, it avoids 80% of common dog food allergens while maintaining 28% protein for muscle maintenance. The rice/carrot fiber blend provides consistent stool quality, and our trials showed 79% of chicken-reactive dogs tolerated it perfectly. Added glucosamine (175 mg/cup) offers joint support - especially valuable for breeds prone to allergies like Retrievers. The probiotic system functions identically to the chicken version for digestive security.

Critical for dogs with confirmed poultry allergies or chronic ear infections. Not necessary for dogs without protein sensitivities. Rotate with other proteins to prevent new allergies from developing.
