Using the KONG EZ Clear Collar is easy. First, select a collar close to the size of your pet's regular collar. Place the collar gently around your pet's neck, making sure there's enough space for two fingers between the collar and the neck. Line up the Velcro strips on the opposite side of the collar and press them together firmly. You can adjust the strips to get a comfortable fit. Remember, don't make it too tight as it might choke your pet. When it comes to maintenance, you can simply wipe the clear, lightweight material with a damp cloth. Keep it in a dry place when not in use. If your pet seems uncomfortable or the collar gets damaged, replace it right away.
