Food & NutritionMelanie: Is Purina dog chow lower quality than royal canin or science diet for example? Please explain.
Purina ProPlan is just as good as Royal Canin and Science Diet, and the Purina you find in the grocery store is lower quality, but it's still the best of the supermarket brands. The reason it is lower quality is because it doesn't use the high quality ingredients, hence the lower price. I hope this helps!
