Fresh, never frozen, super premium rolls with options for all dog breeds, from puppies to seniors and small to large dogs. Our Prime100 Single Protein Diet™ rolls (SPD™ rolls) offer a single source of protein, ideal for dogs with food allergies and sensitivities. We use single proteins in our rolls, such as chicken, beef, lamb, salmon, and kangaroo, known for their limited antigen properties. Quality, purpose-driven ingredients are combined to create healthy, hypoallergenic, fresh rolls, perfect for protein-sensitive conditions like skin allergies & upset stomachs.
