2 in 1 Dog Training Collar Automatic Anti Bark Control with Remote Rechargeable and Waterproof for 2 dogs

This remote training collar is amazing!! It took some time for my dog to get used to what the beep and vibration mean, but now it corrects him immediately (I have not been using the shock on him, as the beep and vibration are enough to correct him). I have a very large dog , and the collar is large enough to fit him well. I highly recommend this training collar!Thank you so much!
