I see these same idiots with the t-shirts on that have chained up and growling Rotties and Pits and they think they are so "tough". There are so many other dogs that are just as tough, if not tougher and could stand up to both of those breeds, but they are owned by animal lovers that bring out the good qualities. Most dogs that are raised correctly, know when it is time to be aggressive and when they need to be mellow. Drake, my Newf, is one of the most gentle dogs around. He loves little kids and both of our cats and is never outwardly aggressive with other dogs, unless they try to steal his toys. But he has no tolerance for wild animals that come on our property. Last night two raccoons were in our garage, fighting, eating cat food and making a mess. As soon as they made any noise, Drake was on the hunt. They couldn't get out of the garage fast enough and down into the garden. Drake flew after them into the dark and I heard some growls and shrieks and I couldn't tell if it was made by dog or coon. I got worried and called Drake. He slowly walked back to the garage and he had blood on his face. It wasn't his and he didn't have any wounds so I was relieved. I hope he didn't kill the Coon, but I hope they don't come back. It is amazing the ability big dogs have to contain the sheer aggressiveness and power they have. Drake has chased off Coons, Bears and Oppossum, yet will gently lick the face of an infant. That is a true tough dog, not some pathetic animal that has been abused by humans and formed into a killing machine.
