Regardless of what I am feeding I know about how many calories both my dogs need to maintain their weight so that is how much I feed in a day. I mix raw meat, sardines, veggies, eggs etc in their food every day and simply make sure that the added food + dry food = their needed calories. I keep calories from added food to a max of 25% of their daily calories as that is what my vet suggested I stay around.
I always recommend people know how many calories their dog eats from their normal food. Makes it so much easier to know how much dry to reduce if adding canned for example.
