1. The downside is that the dog can only digest so much food in a single meal; even if she eats the entire amount, she may not get the full nutritional benefit of the meal.
2. I doubt it. Proteins, fats, and carbohydrates digest at different rates, and she's not evacuating everything with each poop; whatever's left over after each poop, plus additional material, is probably building up.
3. For 5 days, it probably won't be terrible, but it's still not something I would try. It's the same as with humans - holding it increases the chances of an intestinal blockage, infection, and water retention issues.
