Just a note on the Pigga Frigga. I have had two pass through holes. One got the dog and one didn't. I will say it has held up to some good hogs though. After everything I have read on here about vests it seems they can all be penetrated at some point. Overall I really like the vest.
And a pic of my old ugly dog

And a video
