I love dogs and am a bit of a dog whisperer. Every dog that I have ever met that was mean was the result of an owner that should never be allowed to have a pet. Even dogs that tend to be more aggressive can usually be trained to act in a civilized manner. The only exceptions to this are dogs that are basically bred to be natural psychopaths. Personally, the people that do that should be neutered. Where I live it used to be common to breed dogs for pit fighting. That just isn't right. We spend thousands of years breeding that sort of thing out of most breeds and the only way to make a dog into a killer is to basically make them crazy. A lot of the people that used to be involved in that were as crazy and vicious as the dogs that they bred. When you looked them in the eyes they had the same gleam that their animals had. They could easily be Dogmen!!
