Agree with the “shouldn’t be kept as widely” sentiment. Perfect for small ranches and farms , houses with big fenced yards...hunter companion, or as a watch (non- attack) dog, other than that...it is a challenge with potential hazardous risks...despite their loyalty and friendship which is a very strong factor in their favor.
Wow, you guys are ready to throw the baby out with the bathwater. Most dogs are wonderful and harmless, never hurting a soul over their entire lefestime. They are family and never bother anyone (except perhaps the mailman, but just noise). A few, especially a few particular breeds, are predictably bad news. But implying that because of them that dogs in general are dangerous weapons waiting for a trigger to go off seems over the top to me.
