She has been trained on the invisible fence so she is alert the minute the warning beep sounds and stops barking almost immediately

The problem is that if my dog shakes his head like all dogs do it will give a warning beep

If he shakes his head too much then he will get a shock for doing nothing wrong

The strength control is an east to roll gial from to that makes it impossible to know what strength the collar is actually set on and it sometimes beeps by itself

It needs to be extremely tight on the dogs neck and even when fitted properly when a dog is running around or playing it can set this thing off

I put the collar on my dog very tight when i first put it on it did buzz a few times and curbed her barking
