The BigLeash® Remote Trainer is a safe and effective training tool to help you train your dog. Remote trainers are also a great tool for communicating with your dog, even when they are too far away to hear you. The vibration feature is perfect for deaf and hard of hearing dogs. Remote training collars are used to teach and reinforce training commands such as ‘come’, ‘sit’, ‘stay’, and ‘heel”; they can also be used to help correct unwanted behaviors. The BigLeash receiver collars deliver Big Features in a small package. Weighing just 1.6 oz., the BigLeash collar fits comfortably on even the smallest dogs, yet is tough enough for even the most rambunctious tail-wagger.
