I bought this for walking my friend's dog. I don't even own a dog but I like to do things properly. The dog walks much better with me on this than with a collar or Halti. Very pleased. But the main reason I bought this was for it to carry a dog tracker (which I also bought for the dog that's not mine!). I attach the tracker to the grab handle on the dog's back so it is in the best position to pick up the GPS signal, and it is a safe place to put it where I can see it. All in all the harness seems like good quality and hasn't rubbed at all despite the dog being very fine coated with almost no coat under her chest.
