Just saw this guy in some youtube videos. Both dogs are GSD's with issues that are pretty common around here. I've seen similar methods work on lots of pet dogs. I like the things he says about the dog in the second video, about the excuses people make, etc...pretty basic stuff, but I know they are pretty common issues. It's awesome that a dog that originally had to take pills/drugs, can now be drug and stress free AND in such a SHORT amount of time. I know a lot of people are against punishment, but I have seen it "fix" so many dogs, so fast, and then they can move on, living their lives stress free (both owner and dogs). Just another option for people struggling with these common issues (DA, Separation anxiety...leading to destruction).
