A strong 'Ah Ah' or squeaky toys were really all I ever needed, with a follow up of the 'Leave it' command. I kept squeaky toys everywhere for quick access to side track her quickly & often. Substitute what she's doing with something she
can have or do. It all took constant supervision, quick reaction on my part and was exhausting. However, it resulted in her growing up with a strong sense of what's hers and what isn't. We can leave home and not now worry about her destroying anything. To this day, small vinyl squeaky toys are here favorite. Often hard to find them the small size she likes.
We have never had to strike her for any reason. It has been rare to give the 'leave it' command anymore. She just knows.
