Remember to measure for the perfect fit. Eco-friendly and available in a range of colors, the WAUDOG QR Passport Cotton Dog Collar is made from recycled materials, helping reduce environmental impact while keeping your pet identifiable. The collar features hypoallergenic, breathable fabric that retains its look after many washes, wicks away moisture, and helps keep warmth in cooler weather. Reflective stitching improves visibility during early morning and late-night walks. The quick-release Fastex buckle allows for easy on and off, and the included blocker keeps the collar secure during use. Each collar comes with a QR-coded pet ID tag that works with a free app, so others can more easily contact you if they find your dog.
