Review on 🐶 Rechargeable Dog Shock Bark Collar - Adjustable Sensitivity Control for Small, Medium, and Large Dogs - Anti-Barking Collar with Shock & Beep Modes by Tiffany Stone

Works very well. We've been using it on the blue healer for a few weeks now. Healers are very stubborn and have thick skins, but that helped with the barking problem a bit. They stay charged for a long time and pretty much do what they were designed to do. I have noticed that my dog shakes it a lot and sometimes the shaking causes it to beep which confuses it. But since it's just a warning tone and not an electric shock, it's not a deal breaker and it still helps him not bark as much. The shock is enough to make him reconsider his barking, but not enough to hurt him. Overall good value for money. Ps, the toy balls that come with the kit are very small and easy to chew. I was afraid the dog might choke on them so I threw them away.
