What do you people think about my dog?

You seriously need to invest in some training. If your dog is acting this was it's pretty clear that you haven't "brought it up good". A training program will teach you and your family how to properly train a dog. Action definitely needs to be taken ASAP. If your dog attacks a person and is put down by government orders, YOU will be responsible for the loss of an innocent life. There are no bad dogs, just bad owners.
