Safely training your pup doesn’t have to wait until daylight when you have the CollarDirect Reflective Nylon Martingale Collar. Special reflective stitching provides your pal extra visibility during late-night training and potty breaks. The martingale gently creates tension around your pup’s neck when she pulls， then releases when she stops. Soft and flexible nylon pairs with a heavy-duty metal chain and plastic side-release buckles to create a durable collar that can take your furry friend from adventure to adventure! The nylon is not only lightweight and easy to clean， but the vibrant colors won’t fade over time. Choose the best size for your pal after measuring her neck at home， keeping in mind that this specific collar should be a bit wider than her head circumference.
