Summary
Real owners on Reddit have settled on this as their go-to grain-free pick after trying multiple brands. Costco pricing makes it the most affordable quality grain-free option by a wide margin.
Recommended by independent pet food retailers and enthusiast communities for its whole-food ingredient sourcing. One of the few grain-free brands that avoids synthetic vitamins and uses food-based nutrition exclusively.
Pros
- Significantly lower cost per pound than comparable premium grain-free brands
- Salmon as primary protein is well-tolerated by dogs with chicken sensitivities
- Sweet potato as carb source is a gentler, lower-glycemic alternative to corn or wheat
- Widely available at Costco with consistent formula — no frequent recipe changes
- No synthetic vitamins or minerals — all nutrition from whole food ingredients
- Recommended by independent pet specialty stores known for careful brand curation
- Millet used as grain-free carb source instead of legumes, which may reduce DCM risk concerns
- Multiple protein options available including sardine, rabbit, and venison
Cons
- Only available at Costco membership stores — not sold widely online
- Grain-free formula relies on legumes, carrying the same FDA DCM concern as other grain-free foods
- Limited protein variety compared to premium brands with multiple formula options
- Bag sizes are large — not ideal for owners of small dogs
- Less widely available than mainstream brands — primarily found at independent pet stores
- Premium pricing comparable to Orijen
- Smaller brand means less third-party research and feeding trials compared to larger companies
- Millet-based formula still not WSAVA-endorsed
Our take
For dog owners who want grain-free without the premium brand markup, this is the community's quiet favorite — real people feeding real dogs and sticking with it long-term.
If you're deep in the ingredient-label rabbit hole and want a brand that goes further than just dropping grains, Nature's Logic is where serious dog food researchers land.
