Never feed him handouts while you are at the table. Use a squirt bottle or the rattle can if a firm no is not enough. As you use them say NO, or down. Growing pups are always hungry-and you must tell just by how he looks-not by him acting hungry! He just needs to be trained not to jump at the table. I have never given mine "handouts" when I am eating and they don't even think of begging for that reason. It takes time patience and repetition!
