I have other items for sale as well. #Nenechi's Collar is here. #Nenechi's Collar & Leash Set is here. Training for discipline and problem behaviors. This collar is easy for anyone to use, with less worry about accidentally tightening it too much and injuring the trachea. It's also popular for causing less hair breakage. A half-choke collar is easy to put on and take off, and doesn't put a burden on your dog. It's easy to put on, just slip it over the head. This is a matching set of collar and leash. Item Name: Collar & Leash Set Set Contents: 1 piece Color/Pattern: Black Weight: Collar approx. 80g Weight: Leash approx. 140g Material: Polyester Country of Origin: China Size: M (Neck circumference approx. 30-40cm, width 2.5cm) Leash: Length approx. 110cm, diameter 2cm How to use: Quickly tighten the chain beforehand to send a signal to the dogs (what not to do) with the sound and shock. There's no point in tightening it after the behavior has occurred. This is a tool for the owner to anticipate their dog's problem behaviors (pulling, scavenging, threatening other dogs, etc.) and prevent them before they occur. The chain's tightening sensation and sound send the signal, so tighten it quickly and briefly with a "jerk." The movement of the chain is the signal, so there's no point in tightening it tightly and painfully after the problem behavior. *Do not take your eyes off your dog while using. *Be sure to measure the size of your pet and compare it with the sizes above. *Please note that there may be slight variations depending on the type of pet and how it is measured. *There are no other accessories or products other than those confirmed in the actual images. *The product will be packaged in a plastic bag only.
