Your cattle raising neighbor needs to get some information from his local extension office, or local ag. university on use of electric fencing. He's showing is ignorance. Hope he didn't see you with that hot shot, that would set him off!
For one not experienced with cattle, it doesn't matter much whether the animal is a bull or a cow, they can both hurt a human quickly. You can be feeding them and they get excited by the rattling of the bucket and just move over....there you are with a 600# calf a 1100# cow or a 1600# bull. They meant no harm, but you were in the way! You lose!
