Another good thing to do it never allow him to jump on your lap unless
he's invited to do so. If he does put him down on the floor and tell him
to sit. Then invite him up. Teach him to share that bone. DOn't take it from
him but walk pass him and throw a little treat down by it teaching him
when someone comes close to his bone something good happens. Do this
many times during the day everyday until he knows no one will take his
bone. Doggy psychology is interesting. You never get done learning.
