A helpful narcotics dog website for private investigators.
"The answers on this page are my opinions. While they are certainly controversial they are not meant to offend people who take a different position. Over the years I have learned that two people can take a different approach to dog training and both be successful.
I try and answer every question I receive on dog training. I may often come across as a little on the blunt side, (some may call it brash). That is because I consider myself an advocate for dogs and not dog handlers. I am an advocate for common sense dog training and not the latest fad that appears on the horizon. Good dog training is not rocket science. It's common sense."
