Dehydrated Duck Heads All American Canine’s Dehydrated Duck Heads are a nutritious, all-natural treat that delivers both flavor and function. Sourced from high-quality duck and gently dehydrated to preserve nutrients, these single-ingredient snacks are a satisfying, protein-rich option for dogs who love to chew. Dehydrated Duck Heads also support dental health, joint mobility, and mental stimulation. Rich in calcium, phosphorus, and trace minerals, duck heads also support bone strength, joint health, and nervous system function. They contain cartilage and connective tissue that naturally provide glucosamine and chondroitin, which are important for dogs with hip or joint concerns.
