Hickox makes excellent bird dog training videos with an emphasis on safe and sane use of ecollars AFTER the dog understands and obeys commands without the collar. I resisted the use of ecollars, but after having my oldest fail to "hear" me and obey, a trainer taught me the use and Abby's hearing improved within 5 minutes of use. He stresses the importance of order of training. For instance, "whoa" is to be taught before "come" with the collar because if the dog fails to "whoa" unless stimulated ('stimulated" sounds more humane than zapped), the dog will come when you meant "whoa" if stimulated. A lot of good and enjoyable hunting can be had with just two commands: "come" and "whoa". Gil
