my hound dogs the same thing. hounds of course beagles are hounds, too are VERY food motivated. give him something once in awhile but not all the time, because you'll have him in your face all the time.

make him sit before you give anything to him and remember people food isn't that good for dogs even though they like it, it's not good for them.. too much can make them sick. especially junk food like chips aren't good for them.
my hound just looks at me now he doesn't really drool over me and beg anymore, but I will give him something once in awhile.
