Smaller piece size, naturally richer essential fatty acid profile, the friendliest entry point to organ feeding for households of every dog size. The functional whole-food treat that fits the training pouch and the dog's mouth without compromise.

Shepherd Boy Farms is a family operation in Indiana that started as a meat supplier and built the pet line on the same sourcing standards. The chicken is USA-raised under protocols that exclude added hormones and added antibiotics. Every batch is tested by independent laboratories for safety before it leaves the facility. Generic dried chicken liver treats from a pet store rarely have any of this traceability behind them.

The raw liver is flash-frozen immediately to lock in cellular structure, then placed in a vacuum chamber at negative thirty to negative fifty degrees Fahrenheit. Gentle warming under vacuum sublimates water directly from solid ice to vapor without ever passing through the liquid phase. The manufacturer reports approximately ninety-six percent nutrient retention versus the original raw tissue, which is at the high end of what any preservation method achieves. Think of it as pressing pause on the liver at peak freshness. Freeze-dried products retain substantially more nutrition than heat-dried alternatives that destroy heat-fragile B vitamins and oxidize essential fatty acids.

Preformed Vitamin A and the Full B Vitamin Complex

Chicken liver is one of the most concentrated natural sources of preformed vitamin A on earth. Preformed means the vitamin A arrives in its bioactive retinol form, the version the body uses directly, rather than the beta-carotene precursor in plants that dogs convert relatively inefficiently. The body uses retinol to make rhodopsin (the pigment that allows low-light vision), regulate immune surveillance, and maintain epithelial integrity across the gut lining, skin, and respiratory tract.

Chicken liver is also one of the most concentrated natural sources of vitamin B12 in the food world. B12 is essentially absent from plant foods and is required for nervous system function, red blood cell formation, methylation reactions, and DNA synthesis. The full B vitamin complex (riboflavin, niacin, pantothenic acid, B6, folate) supports cellular metabolism and the enzyme reactions that run hundreds of times every second. This is part of why chicken liver has historically been considered restorative food for any animal recovering from illness, blood loss, or stress.

Omega-3 and Omega-6 Essential Fatty Acids, Heme Iron, Copper, Zinc, and Complete Protein

Chicken liver naturally contains meaningful amounts of both omega-3 and omega-6 essential fatty acids (the same family of fats the holistic skin-and-coat conversation has always centered on). Beef liver carries much smaller quantities of these fats, which is one of the meaningful nutritional differences between the two. The whole-food matrix delivers these fats alongside the vitamin A and zinc that also support the skin barrier, making chicken liver functionally distinct for households whose skin program is built on natural fatty acid contribution.

Iron appears as heme iron (bound inside hemoglobin and myoglobin proteins), dramatically more bioavailable than non-heme iron from plants or synthetic supplements. Copper supports the body's antioxidant systems, connective tissue formation, and the melanin that pigments the coat. Zinc supports immune function, skin barrier integrity, and over three hundred enzyme reactions. Naturally occurring taurine supports cardiac and retinal signaling. Crude protein lands at 70.45% minimum on a dry-matter basis, one of the highest natural concentrations in the organ category. For most dogs, copper density is exactly what supports natural pigmentation and antioxidant defense. For copper-sensitive breeds, see the cautions section below.

The Signature Trust Marker

Approximately 96% nutrient retention through sub-zero vacuum freeze-drying.

Generic dried chicken liver from the pet store is usually heat-dried or oven-baked, which damages the heat-fragile B vitamins, oxidizes a portion of the omega-3 and omega-6 fats, and reduces overall bioavailability. Shepherd Boy Farms runs the standard the other direction. Flash-freeze, sub-zero vacuum freeze-drying with manufacturer-reported ninety-six percent nutrient retention, independent lab testing on every batch before it ships. The single-ingredient label is meaningful because the ingredient itself arrives close to the form fresh tissue would have delivered.

You have a small dog whose treat size has been a limiting factor with larger-piece organ treats. The smaller native size of chicken liver means a whole piece can be earned as a single training reward, and the pieces snap cleanly into even smaller portions for tiered training without crumbling in the pouch.

You are new to organ feeding and looking for the gentlest entry point to a holistic whole-food rotation. The smaller piece, slightly more delicate flavor, and added essential fatty acid contribution make chicken liver the friendlier introduction. The broader organ rotation opens naturally from there.

Your dog has chronic dry coat, low-grade skin reactivity, or natural oil deficiency that has not fully resolved on the current diet, and would benefit from whole-food essential fatty acid enrichment in a training-treat delivery format.

You are a raw feeder whose daily bowl already includes organ rotation, and you want a shelf-stable training-pouch option that matches the same whole-food standard without thaw or refrigeration logistics.

You have a senior dog whose coat quality, energy levels, and cognitive sharpness you want to support naturally with whole-food vitamin A, B12, omega-3 fatty acids, and bioavailable amino acids.

You need a high-value training reward for picky-eater conversions, recall reinforcement, or veterinary cooperation work. The intense natural aroma of chicken liver tends to override food refusal patterns.
