Cool Mark! We've used the same fencing system with our goats for almost 2 years now with no problems. We live against a large woods with a multitude of coyotes and haven't had an issue yet. I've personally seen 3 different hunting dogs that wandered onto our property get their noses shocked when they tried to get at our does. You've never heard a dog yelp so loud as when their noses touch that fence. The only issue was when I tried to use it to contain 2 intact bucks, they challenged the fence constantly despite getting shocked. The fencing is way tougher than it looks though, despite the bucks ramming their heads and horns though it on several occasions, twisting it around and tearing it from the ground, the fence still works great.
