Janet, do you use kitchen scale when you cook potatoes for your family ?:) (notice how many poeple don't measure their daily food intake and live to tell about it)
With dogs is pretty much the same, make portions that look right and adjust accordingly when you see dog loosing or gaining weight.:D (and you don't have to feed em exactly the same amount every day, one day bit less, other day bit more won't hurt them).
