I will tell you where I got my info. I can see that different countries and different states employ different training methods. I am only saying what I have encountered, or been told in my area. I come from a law enforcement family... I am not making a blanket statement of all dog units, just what I have learned and seen here over the years.
Your first statement was this
I know how they train K9's and it's not pretty. It's why the dogs are wired and hyper, and they don't live very long.
Thats pretty blanket. You did not specify "where I live, this is my experience".
I do agree there are some terrible K9 programs out there. Some of these people have no idea how to train, and the dogs should never be on the street, but to put all of them in the same category is wrong.
Castlemaid and the others who have mentioned the RCMP are exactly right. It is NOT for show, it is how they trained. They have one of the most respected programs around, and their training is sought after across the country and the world. If you knew me, you would know that I don't compliment the RCMP lightly, it down right kills me. But I do give credit where credit is due. I have seen ALL stages of their training, their demonstrations are not public relations. Pretty much any department in Canada bases their training off the RCMP.
As for the original question, I don't know. Here, you can find the unit training every Wednesday behind the main station, out at the airport and in random neighborhoods. We have had visitors observe, videotape and do regular demostrations. No hiding, no secrecy.
