The forced Usually starts on a table with pain and release of pain once the dog has the propper hold and desire for the object.
It works great if you take the time to lay the proper foundation (many steps) and you cannot half ass it or you will have issues.
As stated by BDBT times and moethods have changed and the positive motivational methods seem to be the best and mostly used technique out there. I like Bart's NePoPo methods ... but it all starts on the training table from day one... and not many people can or will do it right. It all boils down to having the plan and following through on each step to get the best results.
