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.
A Reddit-recommended raw-protein option in dehydrated form — closer to a raw diet than traditional kibble without the handling complexity. Ideal for owners who want raw nutrition in a convenient format.
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
- Dehydrated raw protein format preserves more nutrients than heat-processed kibble
- Multiple single-protein options (salmon, chicken) great for dogs with food sensitivities
- Highly palatable — useful for picky eaters or dogs transitioning off processed food
- Can be used as a topper or standalone meal, giving feeding flexibility
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
- Higher cost per serving than standard kibble brands
- Dehydrated patties require rehydration with water, adding prep time
- Raw-based formulas not ideal for immunocompromised dogs per some vet guidance
- Smaller package sizes mean more frequent purchasing
