That is the reason it works.\nLiver is not a typical treat. It is concentrated organ nutrition with a vitamin A, iron, and copper density per gram that exceeds most of what is on the shelf at any pet store, holistic or otherwise. A single five-gram piece of freeze-dried beef liver carries more preformed vitamin A (retinol, the bioactive form found in animal tissue) than a dog's daily requirement, which is exactly why it works so beautifully as functional enrichment. The holistic feeding rule of thumb is that organ meats should comprise no more than five to ten percent of a dog's total dietary intake on an ongoing basis. The dosing table further down is built around that math.\n\nThis is not a treat to hand out like confetti. This is a multivitamin that grows on a farm. Dosed correctly, it does work no synthetic supplement can match.\n\nShepherd Boy Farms takes the simplest possible approach. One ingredient. USA-sourced beef liver from their Indiana family farm network. Flash-frozen to lock in raw nutrition, vacuum-chamber processed at sub-zero temperatures between negative thirty and negative fifty degrees Fahrenheit, then fully freeze-dried to a uniform, shelf-stable, lightweight piece that holds together in a training pouch without crumbling. Independently lab-tested per batch. No additives, no preservatives, no fillers, no grain, no synthetic anything. What that delivers to your dog is a whole-food source of preformed vitamin A, heme iron (iron bound inside hemoglobin proteins, the form the canine gut absorbs most efficiently), the complete B vitamin spectrum, naturally occurring taurine, coppe","images":["https://cdn.shopify.com/s/files/1/0702/6733/9061/files/CopyofCopyofCopyofCopyofCopyofCopyofCopyofUntitledDesign-17_a29f4636-32c1-4375-b64e-ad07335a8434.png?v=1779462749","https://cdn.shopify.com/s/files/1/0702/6733/9061/files/Copy_of_Copy_of_Copy_of_Copy_of_Copy_of_Copy_of_Copy_of_Untitled_Design_-_287.png?v=1779507848","https://cdn.shopify.com/s/files/1/0702/6733/9061/files/Copy_of_Copy_of_Copy_of_Copy_of_Copy_of_Copy_of_Copy_of_Untitled_Design_-_289.png?v=1779507848"],"price":14.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:36.882Z"},"share_url":"https://firestarter.network/l/lst_3cM85dia","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
