I think I have started something over the Christmas holidays. I'd scramble myself some egg substitute after running each morning, and started mixing a little with Tyke's dry food at breakfast. The substitutes are pretty much egg whites with the fat taken out. Is this ok for dogs? Tyke loves eggs, but I didn't want to give her all that fat. Also, do any of you use other toppings with dry food? She will munch on the dry during the day, but at mealtime, she seems to prefer the eggs in the morning and a little canned food mixed in at night.
