Dog training for aggressive dogs requires one special trainer. I don’t think I would want to be involved in that line of work.
The dog shown in this video is certainly an aggressive dog. But the trainer is able to turn the dog into one with a very sweet disposition.
The key appears to be exercise and developing a good relationship with the dog. This type of dog can be saved.
This is a good video to watch. I hope you enjoy it and share it with your friends. Thanks
