Eating with your animal

I have trained our dog to stay in the porch while I am cooking or while we are eating. It is quite annoying to me to be at someone's house and having their pet beg for food. I made the mistake with my cat over 20 years ago, and vowed to not make the same mistake again. If our dog does get leftovers, they go in his food dish in his kennel. He knows that is where he is to eat.
