Sustainably sourced from Idaho rainbow trout, these whole-prey chews are raised in free-flowing spring water in land-based raceways along Idaho's Snake River. The farms are ASC-certified under the Aquaculture Stewardship Council's Freshwater Trout Standard. Using the whole fish nose-to-tail, they reduce reliance on wild ocean populations while avoiding the microplastics and mercury found there. Freeze-dried trout heads are a powerhouse of nutrients – naturally concentrated DHA and omega-3s for brain, skin, and coat health, plus glucosamine, chondroitin, collagen, calcium, and phosphorus for joints, bones, and teeth. Trout is also a novel protein for dogs with allergies or sensitivities.
