So i own a rottweiler he's 10 months now and whenever he's at home he's fine play's with the kids and is very friendly. Now when i take him to the park he gets very aggressive will bark at other dogs and get very confrontational with them.
So im considering buying an electric collar for him, just so when he misbehaves i can correct him as he has become immune to the slight tap on the nose. I would also like to let him off the leash once in a while so he can have a good run around but obviously not the way he is behaving now.
So has anyone used an electric collar or could advise me which one would be best for a very big chunky rottweiler.
