This is really impressive with all the dogs off lead.Nice to see a bunch of regular folks doing cool stuff! Thanks for posting.
Here is a video that doesn't have Dobermann's, but it's the same basic idea and pretty impressive none-the-less.
Video's like this sure highlight cultural differences. I don't know of any macho LE dog handlers who would be interested in participating in something like this. The American taxpayer wouldn't approve of us doing this here either. However it is still really cool to watch!
This is one of several videos. If you look on youtube you can find the the rest.
