Dog anti-bark collar, USB rechargeable. Purchased on Amazon. Anti-bark collar for dogs, anti-barking device, remote control training collar, rechargeable, vibration, electric shock and beep sound 3 types, dog training, neighborhood nuisance prevention, with Japanese instruction manual (Black) https://amzn.asia/d/0avvSXa2 https://amzn.asia/d/0gfs9jHh Although it has an electric shock function, I switched to using only the sound and vibration functions and used it for training to avoid causing stress as much as possible. I used it about twice a day for a week and then stored it. I bought it because I was worried about my dog's high-pitched barking bothering the neighbors, but it worked for my dog. I will sell it to someone who needs it. Please understand that this is a used item. *It was too long for my Chihuahua, who weighs less than 3kg, so I cut it. After cutting, the maximum neck circumference is about 40cm. - Product name: Anti-bark collar - Accessories: USB charging cable, instruction manual - Color: Black
