No joke Debbie!
When I got my first bark collar they were pretty new and didn't have much control. Just a ZAP that could knock you silly.
Anyhow, the wife picked it up off the table and asked how it worked. I told her it was by voice vibrations when the dog barked.
NOW, my wife is one pretty sharp gal so I had no idea that she was gonna pick that thing up, put her thumbs on the contacts and bark into it.
She started hopping and hollering like a scalded cat. Seems she couldn't let the dern thing go either.
I was laughing so hard I was crying till she finally got loose from it.
Just glad I was 25 or so yrs old and had great reflexes cause I was just able to duck that collar as it went sailing by my head.
Unfortunate that the kitchen window I was standing in front of was closed cause that glass didn't slow down the collar one bit.
When I bought this Dogtra collar about two yrs ago, I had a bit of a time convincing her that it only went off when the button was pressed.
Believe it or not, she's still my best buddy!
