Download our free LED Collar app from the Apple App store or Google Play store by searching for “collar”. Once installed, you can create and share any color pattern you can think of! Our visually apt pattern editor lets you create up to 8 pattern steps with solid color, strobe, and fade effects. All shared patterns can be searched and download in the app, then uploaded to the collar. With a large library of patterns already available, this is the most customizable safety collar you can buy.
