Get a shock collar appropriate for the size of the animal, read the instructiuons for disciplining the animal and follow the instructions. It may sound cruel but it will work. Basically when the dog gets introduced to the tone and shock and a command is given if the dog does not follow the command you use the tone to warn the dog and if she continues to pursue bad behavior your use the shock to reinforce stop behavior.
Believe me it works and it will not take long to resolve the bad behavior when done correctly. This is not over the top as far as correction, if your wife wants to stop the bad behavior and you want a well behaved animal/pet you will be very pleased with the results. Consult with your vet if you have any concerns.

Too bad it can't be used on some of the a$$hats on OT but that's another story.
