This collar is indispensable for you and your dog! The reflective seams make the collar visible in the dark, and the modern design stands out in daylight. The Max & Molly collar combines great design and comfort with high safety. Each collar is equipped with an integrated GOTCHA! dog tag, which has a unique QR code. Using this exclusive and free GOTCHA! Lost & Found App allows you to create a profile for your dog. When the sign is scanned, the person can quickly get the necessary information to reunite you if your dog should have gone missing. The app also provides geolocation of the finder during the scan, so you can locate your pet instantly. The collars are made of sturdy polyester on one side and soft neoprene on the other. The choice of materials makes the collars ultra-light and particularly comfortable for your dog. They also have a safety ring that prevents escape during installation and removal, and the size can be easily adjusted with a plastic slider. With the Max & Molly Matrix 2.0 Neoprene Collar, you're ready for all your upcoming adventures.
