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.
Consistently the first brand Reddit users name when asked for premium grain-free kibble. High protein, whole-prey ingredient ratios, and minimal processing set it apart from most competitors.
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
- Frequently cited as top recommendation in grain-free discussions across multiple Reddit communities
- High meat content with whole-prey ingredient ratios (meat, organs, cartilage)
- Minimal processed ingredients compared to most kibble brands
- Wide variety of protein sources (chicken, fish, red meat) to rotate or address sensitivities
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
- Premium price point — one of the more expensive grain-free kibbles on the market
- Grain-free formulas use legumes/peas as carb sources, which carries the FDA-flagged DCM risk
- Rich formula can cause digestive upset in dogs transitioning from lower-protein foods
- Not a WSAVA-member brand, which some vets flag
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 budget isn't a constraint, Orijen is the grain-free standard — it's the brand enthusiast dog owners keep coming back to when they want the best ingredients without compromise.
