I had a similar problem when feeding my dogs “grain-free” food that still had a LOT of plant material in it from potatoes, peas and various starches. Stools were much larger and more frequent. My dogs now eat a raw food that has only a little plant material and their stools are tiny compared to before.
Most “grain free” kibble replaces the grain with other plant-based calories like peas, potato, sweet potato, lentils, beans, etc. Dogs don’t seem to digest a lot of this stuff as well as one might expect!
