This collar will stop your dog from biting furniture, stealing your clothes, and other bad behavior. The collar will also help you teach your dog to stay close and safe. Designed for long and thick hair, and with memory settings – If the dog’s hair is too long or too thick, the contact points may not touch the animal’s skin. These two metal contact pieces are mounted on the receiver to obtain a good result in dressing. Train different dogs or different movements without adjusting the remote control. Safety lock and reflective strap – The keypad can be locked to prevent accidental static shock, allowing you to carry the remote control safely. In addition, the strap has a reflective coating that allows your dog to be seen by motorists at night. It can be used even in humid places. Note: Please note that the waterproof rubber plug must be securely in place, and avoid leaving the collar in water for long periods of time.
