New dog/ ugly dog vest?

The viper vest is ok - I have two. The material on the front is pretty good, if you have a gritty dog though I would be careful using it. The first time we ran the viper vests one of the dogs took a 3 inch poke through the vest in the sternum area, and the other dog took a poke in the rib cage. I guess they are like any other vest they only protect to a point. But I will say this, without the vest it sure would have been worse. I also have a dog that will hardly hunt at all while wearing it - but as soon as I take it off - he is on fire.
