I actually have all of Cesars DVD's as well. I was recommended them for Betty's aggression and was the first DVD's I ever got. There are some things that are good in his DVD's, but there's also quite a bit that absolutely does not work with Betty. Also, Cesar even says that he's NOT a trainer, but rather that he rehabilitates dogs with big problems.

I'm finishing up watching the Cujo Meets Pavlov DVD's, wow, very powerful stuff. And Kathy is a very good communicator as well, and knows her stuff. I highly recommend this DVD set to anyone with dogs that have some dog-dog or dog-human aggression issues. It's mainly for dog-dog, but you can use the techniques with anything else that's fearful or causes aggression.
