Full Source is a dry-only line of six raw-coated kibbles. Four are With Healthy Grains recipes that use brown rice and oatmeal, and the other two are grain free and use sweet potatoes and potatoes. A named meat or fish comes first in every ingredient list, egg appears in five of the six recipes, and no recipe lists peas or lentils.
Protein runs from 26% in Lamb & Venison to 34% in three recipes, and estimated starch runs from 28.5% to 37.5%, all as fed. The line averages 31.7% protein and 31.5% starch, compared with a kibble catalog average of 26.9% protein and 37.4% starch, so it leans higher in protein and lower in starch than typical dry food. Calories average 386 kcal per cup, close to the catalog's 395.
Lamb & Venison is the exception. It sits just under the catalog average for protein and has the most starch in the line. Most recipes mix several animal proteins, such as chicken, beef and fish, which leaves few options for dogs that need a single protein. Two recipes, Large Breed and Beef & Bison, are listed as discontinued.
