Our LCS Reflective 1” Day-Glo Collars utilize the same long-lasting material as our regular Day-Glow Collars, but these now have a 1/2 inch wide incredibly reflective strip permanently bonded to the collar. We feel our dogs are a lot safer when running at night or any place there are vehicles with these reflective collars. Remember to measure your dogs neck size for an accurate fit. Available Colors: Blue, Black, Green, Orange, Pink, Red, and YellowWidth: 1 in.Lengths: 15 in., 17 in., 19 in., 21 in. How to Measure Your Dog’s Neck for Our Reflective Dayglow CollarMeasure the circumference of your dog’s neck using a cloth tape or a string. You want your dog’s collar to be snug, but not too tight. Make sure to measure for the correct tightness.Match up your measurement with our LCS Reflective Dayglow collar. Our collars are measured from the buckle’s post to the center of the five holes (as pictured below). They are NOT measured by total collar strap length.Our collars come in odd lengths (13, 15, 17, 19, 21 inches). If your dog’s neck measures on an even number, we recommend rounding up to the next odd number. You can always add a hole that is smaller or trim excess strap, if need be. As reference, a 15” collar will fit neck sizes 13-17”.Free Custom Engraved Brass Name PlateAdd an optional machine stamped brass name plate to our LCS Reflective DayGlow collar.
