FAQs
How much Pro Plan should I feed my dog?
A 50 lb adult neutered dog needs approximately 985 kcal/day. At 355 kcal/cup (Pro Plan Adult), that’s about 2.8 cups per day (1.4 cups twice daily). Always verify by checking the specific variant’s calorie statement on the bag.
Is Purina Pro Plan better than regular Dog Chow?
Pro Plan uses higher-quality protein sources and more targeted formulations for specific life stages and health conditions. Dog Chow is a solid everyday option at a lower price point. Both are nutritionally complete and AAFCO-approved — the right choice depends on your budget and your dog’s specific needs.
