Frequently asked questions
What's the most important nutrient in puppy food?
DHA (docosahexaenoic acid) — an omega-3 fatty acid essential for brain and retinal development. Puppies can't synthesize adequate DHA on their own. Purina Pro Plan sources DHA from fish oil, which has superior bioavailability compared to plant-derived ALA. Studies show measurable differences in cognitive development scores with DHA-fortified puppy food.
Should large breed puppies eat a different food than small breeds?
Yes — this is critical and often overlooked. Large breed puppies (expected adult weight 50+ lbs) need a lower caloric density and a specific calcium/phosphorus ratio to prevent too-rapid bone growth, which is a risk factor for hip dysplasia and osteochondrosis. Always use a large-breed-specific puppy formula for dogs that will exceed 50 lbs as adults.
When should I switch from puppy to adult food?
Small breeds (under 20 lbs): 9–12 months. Medium breeds (20–50 lbs): 12 months. Large breeds (50–90 lbs): 12–18 months. Giant breeds (90+ lbs): 18–24 months. Switching too early deprives your puppy of growth-phase nutrition. Switching too late in large breeds can contribute to excess caloric intake.
Is raw or fresh food better for puppies?
Fresh food (like The Farmer's Dog puppy formula) can be nutritionally excellent if AAFCO growth standards are met. Raw food is higher risk for puppies due to their developing immune systems — Salmonella and E. coli contamination is more dangerous in young dogs. If choosing fresh, stick with cooked human-grade options from regulated kitchens.
How much should I feed my puppy?
Puppy feeding guides are typically split across 3–4 meals per day (not 2 like adults) until 6 months, then 2–3 meals until 12 months. The package feeding guide is a starting point; adjust based on your puppy's body condition (ribs should be felt easily). Puppies self-regulate poorly — controlled portions prevent the overconsumption that leads to joint problems in large breeds.
