Lean pork loin makes up 80% of the slab — trimmed of excess fat and cooked plain, it's a complete protein that provides all the essential amino acids a dog needs, and it's easy to digest, so it's less likely to cause stomach upset when the fat is properly removed. The remaining 20% is pork liver, and it's doing more work than its size suggests. It's a natural source of vitamin A, B vitamins, iron, and zinc, supporting immune health, energy metabolism, and red blood cell production, the kind of dense nutrition a lean cut alone doesn't carry. Its rich flavor is also the reason most dogs go straight for these cubes first in a training pouch.

It's not two proteins doing the same job. It's leanness paired with density — the loin keeps things light, the liver fills in everything a lean cut leaves out.
What you end up with is a full slab that scores into 160 tiny training cubes — light enough to use often, with just enough liver folded in to make every cube worth chasing.
Lean protein. Nutrient-boosted. Cut fresh, not processed.
