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

The logistics is very fast, and I brought it to the dog as soon as I arrived. Otherwise, it's always a little uneasy to let go of the dog. He always runs around. With the locator, he knows where the dog is at any time. It's very convenient to find the dog, and the map can be seen clearly.
