The product description 1. Sturdy Dog Collar built to the end - Our chewable is built using thick tear and wear ballistic nylon with user-friendly side release clasp for easy opening/closing. By manufacturing high tensile strength 3M reflective stitching and aluminum D ring traction clips, we create a combination of durability and strength. 2. Integrated ID dog tag attachment - no longer lose engraved dog tag or chip ID. Our integrated ID tag attachment point is separated from the metal belt clip to ensure this ID collar stays quiet.

Designed for comfort and safety - Our reflective nylon mesh provides maximum air permeability for hot summer activities. Embedded 3M reflective pins can help keep an eye on your dog in low light. Plus, when you walk near the road, you'll enjoy better nighttime visibility. 4. Convenient sizes for each breed - Not just one for large dogs, this tuff is available in 4 sizes to fit all dog breed sizes. Choose the correct size based on the circumference of your dog's neck.
