The Ultimate Dog, Puppy Pet Collar for Safety, Comfort and Style.Have you ever lost your peteven for just 5 minutes? We believe that every collar should have an ID tag with info needed to reunite you and your bestie. That's why we have developed our exclusive Lost Pet Protection Program.Every Max Molly Collar comes with a Gotcha Smart ID Tag. Create a free profile with contact info and relevant details about your pup. If lost, the finder simply scans the QR code on the tag with their smart phone and instantly has access to help reunite you and your pet with the use of geotracking technology. Additional safety benefits: Safety Ring – Much like a traditional D-ring, its function is to attach to leashes and other accessories. However, its shape and placement have been designed to catch on the buckle to prevent your pet from slipping out/escaping when you're taking off/on your dog's collar.Let's Talk About Comfort.Every collar is crafted with a thick and plush layer of neoprene wrapped around a durable band of nylon, sewn together with precision stitching. Neoprene is an extremely tough and versatile material that is super soft touch – making these collars an excellent choice for dogs with sensitive skin. The many wonders of neoprene make these padded collars comfortable, ultra-strong, lightweight, waterproof, quick-drying, and more! *Sizing:XS - Width: 3/8" | Length: 8.7-13.8"S - Width: 5/8" | Length: 11-17.7"M - Width: 7/8" | Length: 13.4-21.7"L - Width: 1" | Length: 15.4-24.4"
