Young Aussie who would bark out of excitement getting into the truck, meeting visitors etc. Took 2 days to train him not to bark But! He's an Aussie, took him zero days to figure out that when the coolar isn't on he can bark his heart out without the beeping and buzzing. Would work great on a lab but.....

I wish I could give this more stars however it unfortunately doesn't work on my 90lb. female AT ALL. It was worth a try I guess.

I have purchased three of the Bark Boss collars for two of my dogs. The first one lasted about two and a half years but due to how much she wears it, the dial finally wore out and would not change settings. Currently I have one for my lab and mal. Both work great, but the only issue keeping it from 5 stars is that the dial does not have a locking feature for the level of intensity. Several times my lab has had the dial turned up, been stimulated at a close to max setting (he’s very easy and only needs a 2). Also, it has been activating when he scratches at his neck.

Worked immediately on my yellow lab. We can let her outside for longer now without worry.
