I’ve only used the beep and vibration so far (no shock) and it’s getting his attention enough to stop the nonstop barking

Our dog has never been shocked, the beep and vibration have been enough to stop the barking

We have tried many bark collars and our dog gets used to them and just ignores the beep and vibrate

The beeping is not too loud but is now enough to stop our dog from barking

The never got to where a correction shock was needed because of the solid beep and the strong vibration.

It only took ONE beep, then vibrate combination for my 9lb Morkiepoo to learn that when the collar is on, barking isn’t as fun

Vibration and beeping combo initially worked, but quickly our dog ignored it and barked right through.

Loud beep & strong vibration mode
