I was fortunate that my dog responded amazingly to a whistle. My buddy had a beagle that needed the e-collar for 3 years before settling down enoughI use an ecollar when I hunt my dog. When she gets out too far I give her the tone/vibrate. It stops me from yelling commands. Some dogs range a bit and yelling for them is not ideal, id rather just be quiet and use the collar.
If the tone doesn’t work then she gets the lowest stimulation setting and usually that does the trick. My collar has never gone above the 2 setting, that’s usually when the dog starts to hunt for herself and needs a quick tap reminder to stay closer.
I find some breeds are just laser focused on hunting and once and a while need to be brought back to earth
Those that say ecollars are not needed have likely not worked with high strung big running thoroughbred type dogs whose whole focus is to get game.
