NAMED ANIMAL PROTEIN
Pork Lung
The lung of the pig, an organ meat.
Why It Turns Up In Dog Food
- A very lean organ meat, high in protein and iron and very low in fat.
An ingredient on its own tells you very little.
What matters is how much of it there is and where it sits in the list. That is why we weigh
the top five rather than reacting to any single name further down.
