my puppy who is 4 months old tends to sit at peoples feet begging for their food.  He eats, but what do i do to teach him to not beg?  I dont want people eating and him at their mouth trying to get their food.  what to do...................

What my brother did with all his German Shepherds is to NEVER, EVER feed them ANYTHING that is not in their food bowl......EVER.  You must however request all family members and visitors abide by this rule.  He swears it works.  If a dog only get food in his bowl, he will soon learn to only expect it there.

Of course, that's a lot easier said than done.  I give my dogs the occasional treat from my hand and in doing so, they have come to "hope" this may be their lucky day.  But they don't jump up for it or beg.  They just sit and hope.  

The never beg at the dining room table either, because I NEVER, EVER feed or pet them at table.    Zipper sits quietly under the dining table (hopeing a piece will fall) and Button doesn't even come in there at all during meals.
