Review on 🐾 Enhanced Wireless 2-in-1 Dog Fence and Training System for Dual Dogs, Advanced Pet Containment System, Dual Collar Wireless Dog Fence by Tina Wells

We bought this and tried it on our 9 month old pup, unfortunately didn't work, he sat on the border until the battery died and then he ran away. It would never shock him, but it would really shock us if we tested it. So we decided to send it back and get a second one in case it was the device itself. After receiving the second one I can add it was delivered very quickly without returning the first one. We set it up and tried it out, it seemed to work, but only on the first day, then it didn't work, even at a high level, apparently the "shock" had no effect on our stubborn dog. We went to Petco about a month ago, bought their 3/4ace wireless dog collar and have had no problems or a stubborn dog since. Not sure if it was the device or the dog, anyway we tried TWO and they were both defective, now I'm waiting for a refund.
