i have a catahula male thats a helleva dog just one problem he fights ive try shock therapy doesnt seem to do any good but after he starts it the dogs that are not aggressive at all towards other dogs want to fight him cant seem to pair him with any of my other dogs without a fight hate to cull good dog that hunts finds hogs but it is to that point any other options i can try before he is culled
so far the best way I know to break the dog or to get better control of him is to put an ecollar on him as well as the other dog and set them up to where there will be dominance issues...light him up until he submits...and get on the other dog as well...
what could be happening is that the dominant dog is getting disciplined and the other dog is left alone because he didn't start the trouble...this dog will then instigate trouble just to see the other dog get hammered...so both need the treatment and you will see a big change for the better with the dominant dog...
