After trying almost every dog harness made, I can say Bravo! The frontline harness is the best I have found for my trailing and scent detection needs. Other harnesses ride too far sideways when the dog pulls right or left. I also appreciate the low profile metal d-ring. I can’t tell you how many times, I have had to try to free a dog who has gotten caught on a branch or other protruding object while working in a harness with those giant d-rings. After almost losing a dog on a busy street by backing out of a harness with fewer straps, I appreciate the extra strap on this harness. The material is light weight yet durable. Please keep offering a grey or black color for individuals working in fields where bright colored dog gear is discouraged.
