Using this collar is easy. First, measure your dog's neck to figure out how much of the collar you need. Then, use a pair of scissors to cut the collar at the holes for a perfect fit. When walking your dog, especially in the evening or early morning, this high - visibility collar will make sure your dog is easily seen. As for maintenance, since it's soil - and odor - resistant and water - repellent, you can just wipe it clean with a damp cloth if it gets dirty. Remember, never try to burn the collar as it can damage the material and make it unsafe for your dog.
