No, you do not have to add anything to a complete and balanced kibble for your dog to get all its required nutrition. However, I feel better adding fresh, less processed food to it. I feel like it’s just a little healthier. There is a download on dogwise.com called See Spot Live Longer by Steve Brown that was helpful to me for ideas and amounts to add to kibble. Also there is info on dogaware.com on the subject.
I rotate adding canned, eggs, tripe, commercial raw and sardines to their kibble meals. Just remember if you choose to do this, decrease the amount of kibble being fed to avoid over feeding. Good luck!
