If you are counting on the probiotics or enzymes in the food being of benefit to your dog then you should only add water that is warm, not hot, and add it immediately before feeding. If you are adding extra probiotics or digestive enzymes then wait to add them until after the food has started to cool, and feed immediately after.

I always add 1/2 cup ofwater and 1/2 tablespoon of raw apple cider vinegar per cup of food.
