Pet Food Ingredient
Natural Flavor
Generic label term for a palatability additive that must be derived from animal or plant tissue under AAFCO rules — typically a rendered animal digest that boosts palatability. The source is rarely disclosed on the label.

Regulatory status
AAFCO requires any ingredient labelled "natural flavor" to come from an edible, animal-derived or plant-derived source. Specific species sourcing is not required on the label.
Key notes
- —Usually poultry-derived when the finished food contains any poultry elsewhere. This is why "chicken-free" labels can still contain natural flavor that triggers chicken-allergic dogs.
- —Brands specifying "natural chicken flavor" or "natural beef flavor" are more transparent than the generic term. If the label only says "natural flavor", assume it could derive from the same source as the primary protein unless proven otherwise.
Common questions
What does "natural flavor" mean in pet food?
AAFCO requires "natural flavor" to come from an edible, animal-derived or plant-derived source — but it doesn't require species identification. Most commonly it's a rendered animal digest (often poultry-derived) added for palatability. Brands specifying "natural chicken flavor" or "natural beef flavor" are more transparent; generic "natural flavor" could be any source.
Is natural flavor safe for dogs with chicken allergy?
Often not. Generic "natural flavor" on pet food labels is frequently poultry-derived — particularly if the finished food contains any chicken or turkey elsewhere, since the same supplier often handles both. A food labelled "chicken-free" with "natural flavor" on the ingredient list can still trigger chicken-allergic dogs. Contact the manufacturer for source verification if the label is ambiguous.
Is this ingredient in your pet's food?
Scan the label. If it contains natural flavor or any of the alternative names above, the scanner will flag it against your pet's allergen profile.
