I have read that since lamb is more expensive than Chicken the lesser quality brands will build up the fillers, so you really aren't getting as much lamb as you would chicken. but here is canidae breakdown vs Nutro (everyones favorite today).
Canidae's main ingredients- Lamb Meal, Brown rice, Canola oil.
Nutro's main ingredients - Lamb Meal, Ground Rice, Rice Flour, Rice Bran, Rice Gluten, Poultry Fat
Poultry fat is considered non- specific, it isn't chicken folks! - see the last paragraph if you really want to know...
