Using this collar is simple. Just adjust it to fit your dog's neck comfortably. When putting it on, make sure the buckle is securely fastened. For safety reasons, don't use this collar with a leash or tie it up. If the collar gets caught on something, the buckle will release, letting your dog get free. To keep the collar in good condition, clean it regularly with a mild soap and water. After cleaning, let it dry completely before putting it back on your dog.
