Review on Regal Dog Products Heavy Duty Reflective Dog Collar - Adjustable with Durable Metal Buckle and Rings | Anti-Odor, Chew Resistant, Waterproof Collar for Small, Medium, Large Dogs by Angie Love

I switched my dogs from nylon collars to these because we live in a place that gets a lot of rain and their collars smell horrible when wet. They saved us from unpleasant odors and none of them showed any signs of wear other than cosmetic (scratches etc.). I can't comment on their reflective properties as we have a large yard so we're not going out for evening walks or anything like that, but the reflective strip is still there as it was when it first appeared. It didn't fade or go away. We have one for our 80 lb German Shepherd and one for our 45 lb Border Collie.
