If I take my pup to protection training will I be able to have people come over without putting my dog away? Is there a difference from guard dog and protection dog?

If your dog has good nerves, stable temperament and excellent training you should be able to control the dog when people come to the door. In my opinion, a guard dog is a dog that is kept behind a barrier to keep people out of an area, no matter who that person is. A protection dog is a dog trained to protect the handler or home and is directed by a person. These are MY definitions and other people may have different ideas on this topic. I suggest you take some time and read through our free articles. Here are a list of videos we recommend if you wish to train a personal protection dog.
