"I have 8 dogs and this is the only way to safely leash walk them. The cheap "discount store" harnesses do not fit correctly, this one stays out of their arm-pits. I have control of their front legs / shoulders, not just the head / neck for walks and training. This also holds them in the car seat by adding a seatbelt attachment, and if anything happens it hill not harm the neck.
The one that was a chewer needed a 2-ply harness and I had to put banana oil on it to break him from chewing on it. I will not use a regular collar again."
