Adult Dry Dog Food Lamb & Rice 5 lb vs Size Health Nutrition Large Breed Adult Dry Dog Food: which is safer?

Where these two actually differ

• We flag Mineral oil or ink migration from paper and Mold or bacterial growth from moisture ingress on the Purina Pro Plan and not on the Royal Canin.
• We flag Moisture barrier coating composition and migration, Mold and mycotoxin contamination if bag integrity fails, Cardboard recycled fiber contaminants (printing inks, legacy chemicals) and Oxidation and nutrient loss if bag seal degrades over time on the Royal Canin and not on the Purina Pro Plan.
• The Purina Pro Plan is paper/kraft outer bag with likely polyethylene inner lining (food contact) where the Royal Canin is Paper/cardboard bag (standard dry pet food packaging), which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
