If your dog's stool has a different color, it's simply the result of new enzymes in the diet-- and nothing to worry about!
You may also notice some undigested ingredients in their stool. This isn't problematic, and shouldn't prompt concern as there are still plenty of nutrients within the diet, unless you're seeing the bulk of the ingredients look completely undigested. If this is the case, it may be a sign of an underlying medical condition, and you'll want to contact your veterinarian.
