This is my second purchase of the Front Range dog collar and harness. First set purchased over 5 1/2 years ago and worn almost every day since. My 18 lb. dog is extremely active and energetic. He walks, runs, plays and roughhouses with dogs 2 to 4 times his size. I can't state enough how durable, comfortable and long-lasting this harness is. It has been hand-washed and scrubbed dozens of times.
Once adjusted to fit, the straps don't loosen up, and I've never had to worry about him slipping or pulling out of harness.
Functionally, there is nothing wrong with old harness other than some color fading and slight fabric wear under chest piece. I just want my pup to always look his best!! Highly recommend the Front Range Dog Harness.
