Using this database of the ingredient decks of dog and cat foods on sale in the United States, we did a thorough analysis of the recipes to determine just how widespread the grain-free movement is in pet food.
In dry dog food, 44 percent of the recipes in the database do not contain grains. These grains include all forms of corn, wheat, rice, soybeans, oats, millet, flax, barley and sorghum.
Of these grain-free recipes, 28 percent have grain-free in their product name or in the formula name. We define names as broken into brand name, product line, formula, and stage. So for example, “Blue Buffalo Basics Grain-Free Adult” has identified itself as grain free in is formula name.
Of the grain-free dry dog food recipes, 50 percent of them contain peas, 23 percent contain chickpeas, and 14 percent contain lentils.
Some brands are more heavily invested in grain-free than others, but 78 percent of the brands producing dry dog food in our database have at least one grain-free formula.
The percentage of recipes using these common alternatives to grains is nearly the same between dry dog and dry cat foods.
Examining dry cat food, the numbers are similar -- 47 percent of the recipes do not contain grains.
