This was one of the very first training DVDs that I did back in the early 1980's. The video was produced from video of a Bernhardt Mannel training seminar. Bernhard was a SV teaching judge. He was one of the first training/instructors to come to this country and teach the prey method of protection dog sports. He was in his early 60's at the time and has sin ce passed away. Bernhard did not speak English and it was difficult to find translators that understood the terminology of the dog sport. But in spite of this shortfall we seemed to learn from him. The reality is that Bernhardt Mannel was one of the founding fathers of protection dog sports in America. He helped bring training protection dogs out of the dark ages where guys in big puffy suites put dogs into fight or flight to get them to bite. The image quality of this streaming video is nowhere near the quality it was when it was originally filmed. It is also nowhere near the quality of our current Leerburg training DVDs. Many of the older dog shows and competitions were not encoded into a computer format until the video tapes were 20 to 25 years old. Over the years, the image quality of video tape deteriorates. These older dog shows are being offered for their historical significance. That's why we are streaming videos for its current price which originally sold for up to $100.00. These videos are no longer offered on DVDs.
