A level teaspoon brown sugar is all that's needed. Brown sugar dissolves easier than granulated, but the granulated is just as good. Could also add just a little bit of grated sweet potato or carrot or canned pumpkin. Just a little if you don't want the whole thing to become a sugar bomb. Canned pumpkin is good for dogs too, not too much, but when I open a can, I freeze it in portions to add to the dog's food. Auggie is only 7 pounds, so his portion is very small. :) One of those frozen portions added to the chili would eliminate the processed sugar and add just a squeak more fiber and nutrition.
