Yes 10% is the same amount whether you work it out daily, weekly or monthly
. Totally up to you and your dogs how often you feed organs, as long as they make up around 10% of the total diet. It is easier to feed a couple of times a week alongside their bony meals. If you are feeding bone every day, then organs every day might be best too. Just keep an eye on the poo. If it is too loose, it is either too much organ or not enough bone.
