I recently stayed with some people who have a rotweiller dog. I was concerned and asked if the dog was dangerous. They said no it has the personality of a labrador. However because they have a large property they have the dog as a guard dog. At first the dog was ok but then suddenly the dog went for me and I was very scared. Should I have reported the dog? What if the dog went after a child? It is all very well to say the dog as the personality of a labrador but if it a guard dog what is the use of that if there is an intruder? Because these people were so nice and upset at what happened which thankfully nothing serious happened I was reluctant to take matters further. However they said what I should have done was put my arms up and shouted down to the dog. This means that the dog has a tendency to be fierce because otherwise they would not have said that is the command when the dog gets over excited or comes at you so if the dog is as gentle as they first made out then why is the dog for guard purposes and why would the dog be trained to follow such a command and stop coming at you? They must know the dog can be unpredictable so they have trained it to follow the shouting down command but they said oh no our dog is fine and gentle. I almost said if the dog is so gentle it would be no good if there was an intruder because the dog would just roll over and expect the person to stroke it
