grain-free no fillers, additives or artificial preservatives sourced & made in the U.S.A. Herbsmith Smiling Dog Dry Roasted Pork Liver Dog Treats are meat-based with balancing vegetables and fruits. We add no grains to replicate a more natural diet! Smiling Dog treats are different. Made with no grain, fillers or artificial preservatives, Herbsmith's Smiling Dog treats help dogs live naturally. Dogs are scavenger carnivores, designed to primarily eat and digest meat with some vegetables and fruits or little to no grain. That's why Smiling Dog has real food treats made with simple basic ingredients based on a dog's optimal diet. At Herbsmith, we feel that pets should not simply eat to live… they should eat to thrive! The right diet can bring your dog into a whole new state of health and wellness.
