1- Making total mess
If your dog is constantly jumping around, going for other dogs, pooping in every corner of your house and destroying your furniture, or just generally causing a lot of messes, then it is a clear sign that he is not happy with you and that he feels like you are infringing on his territory. This is a common problem, especially in larger breeds such as German Shepherds and Rottweilers. The first thing you must do when you think that your dog is scaring you is to determine the cause or causes behind this behavior. If you are lucky enough to find out that another dog is caused by another dog or maybe even another breed of dog, you will need to take measures to correct this problem and stop your dog from getting hurt.
