1. 01

   Adds herbal flavor

   Parsley is grown as a culinary seasoning, and dehydrated leaves retain some characteristic flavor. Its role in dog food is seasoning, not a main source of protein.^6,9

2. 02

   Adds green color

   Dehydrated parsley retains green color. Cut leaves leave visible flecks in a recipe, while finely milled parsley gives a more even tint.^6,11

3. 03

   Supplies a storable herb

   Drying lets suppliers pack parsley as flakes or powder for bulk shipment. Manufacturers can measure dry material into production runs without storing fresh leaves.^7,11

How much A typical kibble amount is not published; one dry dog food declares 0.07% dried parsley.⁹
