These are single-ingredient dog treats made from 100% grass-fed beef liver, freeze-dried into firm bites. The formula is as simple as it gets: one protein, no grains, fillers, preservatives or added flavoring. That makes them a fit for dogs with food sensitivities or owners who want a clean, high-value training reward. Against rival liver treats, the freeze-drying keeps them light and shelf-stable without refrigeration, though the pieces are firm and crumbly and the liver smell is strong.
