Here is a silent vs. open twist for you, walk hunt from the truck next time you go to the woods. I will promise you more hogs caught and they will be closer to you haha. They can hear the buggies too!

Thats it. Any extra noise, no matter what it is, will move the hogs out of the area here. They have been conditioned to know barking dogs = people and death.
Plus, I don't see how you get catch dogs lined up when the bay dogs have been barking the whole time. Guess you can send them on command or some thing?

If the hog breaks and the dogs are barking on track the catch dog will probably try to keep going. I want the catch dog to come back if it gets quiet.
