Cesar's stuff can be really helpful (I'm a huge fan), but I think a lot of his advice falls into one of two categories: 1) making sure the dog gets adequate exercise and 2) correcting problem behaviors as they occur. (While also being aware of what you are projecting to the dog) Which you have to be present for.

It's a bit harder to correct behaviors that occur when the dog is unsupervised. Adequate exercise helps, but it may be that further dog-proofing the garbage or finding a way to confine the dog to a non-chicken-bone part of the home when you are out would be most expedient and effective.
