I would like to add that the e-collar is for correction. You must first teach the command and have the dog understand and know the command before you can use the e-collar to make the correction. And remember as well 90 to 95% of dog training is praise. A good Boy/Girl and a pat on the head or a rub on the belly go along way. Once the Dog finds out that I do "A" then I get praised if I do "B" no praise A is looking pretty good to him because you like what he does and he wants you to give that praise. I agree with the statement and also use innotek I have a GSP and really like my Track and Train Beeper collar.
