My boyfirend and I recently moved to a new place and ever since, our dog completely knocks over his food bowl when we are gone. Before this when we would leve him alone he would eat his wet food and then eat all the dry. Now he only eats the wet and detroys his dryfood bowl. WHY? Has anyone dealt with this before?

It sounds like he is going through an adjustment phase himself. When you leave the house, is it for a long time? If it is only for a few hours, I would try putting his dish up where he can't reach it until you get home. You can try this until he gets use to his new environment.
