Review on Rechargeable Bark Shock Collar for Large Dogs | Adjustable Sensitivity & Intensity 🐕 | Anti-Barking Collar with Beep & Vibration | No Bark Collar for Medium Dogs by Lorenzo Moulton

I have found my dogs can still bark a lot before this collar activates and beeps. There are times when my dogs have a few barks, it doesn't do anything at all. Very rarely does it really work with the first bark. I installed them tightly according to the instructions and still no improvement. Not sure if this really helped my dogs, they know they can get away with a lot and have learned what barking sounds don't activate the collar. A couple of times this worked, my dogs were a bit calmer, but overall I was shocked at how difficult it was to get these collars to pick up bark. Edit: After posting this, I received several emails from the supplier about how they would refund me for the product and asked me to retract my review. I have not received any returns. So now I'm being harassed and making promises that aren't being fulfilled. Yes, and bark collars still require a few barks to activate, even on the most sensitive settings. A disappointing collar and a company to work with. Very unprofessional and annoying.
