I have been training dogs all my life, it seems, but seriously since 1970. I have seen training methods, both good and bad, come and go over the years. I crossed over to totally positive methods in the 90's and have been relearning to train ever since. I currently work with 4-Hr's as well as my own dogs. They are all seniors right now - collie, afghan hound & std. poodle. Training tips always welcome!
