Bo has had obedience and therapy dog training, but we still have "Beware of Dog" signs up on the gates to the back yard. He like people but I still keep him on a short leash when we're out walking around a lot of people. He is very defensive about his/our home and property and judging by how fast he goes through a nylabone if he ever really bit someone he could do some very serious damage. I'm cautious by nature with him just because I don't want to frighten anyone, most people are already wary of him just because of his size. We have a neighbor who got a German Sheperd pup and it's killed a few of his chickens and ducks and regularly gets out and wanders the neighborhood,a pretty rural area. Now he wants to adopt a Mastiff, he likes big dogs. I just wish he were a better owner. Any dog, if not properly trained and cared for, can be a problem, even "rug rats" let alone something the size of a Sheperd or Pit Bull. Some people shouldn't have pets at all but you can't cure stupid.
Off the soap box.
No we can't.
