Puppies grow fast — and they need food that keeps up. Too much calcium and large breed puppies get joint issues. Too little protein and small breed puppies lack energy.
I didn’t have Luna as a puppy, but I tested these foods with a neighbor’s litter of Golden Retrievers. Here’s what works for each breed size.

Detailed Reviews
1. Blue Buffalo Life Protection Puppy
Price: $52.99 | Check Price on Amazon →
Best for: Most puppies — balanced nutrition with DHA
Blue Buffalo’s puppy formula includes DHA for brain development and their LifeSource Bits with antioxidants. The kibble size is appropriate for small to medium puppy mouths. My neighbor’s Golden Retriever puppies had great energy and consistent growth on this.
⚠️ Caveat: Large breed puppies need a specific calcium ratio. Check with your vet for giant breeds.
Verdict: The best all-around puppy food. Great for small to medium breeds.
2. Purina Pro Plan Puppy
Price: $44.99 | Check Price on Amazon →
Best for: Large breed puppies (controlled calcium for joint health)
Purina Pro Plan’s large breed puppy formula has controlled calcium levels specifically for big dogs — critical for preventing hip dysplasia. Includes DHA and natural probiotics. The kibble is on the larger side, suitable for big puppy mouths.
⚠️ Caveat: Contains by-product meal. Kibble too large for toy breeds.
Verdict: Best value large breed puppy food. The calcium control alone is worth it.
3. Hill’s Science Diet Puppy
Price: $47.99 | Check Price on Amazon →
Best for: Vet-recommended, great for sensitive stomachs
Hill’s is what many vets recommend. The formula is balanced for all breed sizes and includes DHA from fish oil. Highly digestible — the neighbor’s puppies had very few digestive issues compared to other brands.
⚠️ Caveat: More expensive than Purina Pro Plan. Ingredient list isn’t as ‘clean’ as Blue Buffalo.
Verdict: The safe, vet-backed choice. Especially good for puppies with delicate stomachs.
Other Products We Tested
- Royal Canin Small Puppy: Tiny kibble perfect for toy breeds. Expensive but kibble size alone is worth it for Chihuahuas and Yorkies.
Choosing Puppy Food
- Breed size matters — Large breed puppies need controlled calcium. Small breeds need calorie density.
- DHA is essential — Look for DHA from fish oil for brain and vision development.
- Kibble size — Tiny kibble for tiny mouths. Oversized kibble can be a choking hazard for toy breeds.
FAQ
When to switch to adult food?
Small breeds: 9-12 months. Large breeds: 12-18 months.
Can puppies eat adult food?
No. Puppy food has more protein, fat, calcium, and DHA that growing dogs need.
Final Verdict
Blue Buffalo Life Protection Puppy for most puppies. Purina Pro Plan Large Breed if you have a big dog.
