This bark collar automatically adjusts for your dog by adapting to how frequently your furry friend barks. We call this built-in technology "temperament learning". For example, when your dog barks, he will receive the shortest correction sound from the collar (1.5 sec). If he continues barking, the timing will increase gradually through 10 levels up to 4 sec, but if he remains quiet, the levels of correction will automatically get shorter. Because the correction is immediate and consistent, your dog will learn to associate his barking with a correction and change his behavior.
