What is effective at guarding goats from dogs and coyotes? I have 2 Jacks that I put in the pasture with them and the other night I came in a dog had killed 2 kids and a mama and was still eating on one when I got there. The donkeys where just watching. That dog no longer can eat goats or anything else, but I need to find something to keep them safe. My fencing it a 6 strand hightensile with a 3 joule gallagher charger. Most dogs have found that they can just run through it and get through before the next pulse hits. Do the dogs like Great Pyrenese have to be trained to guard?
