To "Dave" who responded with this:

"With so many screwed-up and dangerous people out there these days you would be crazy not to have a protector around your home and if you must chain them-up that's what you must do.I have such an animal. I resuced it from an abused life. It was beaten starved 60lbs with ribs showing through his sides.Now it's been 3 years he's 90 lbs and has his confedence back. My vet asked us what we did to bring him back to such good health(love,care and attention)He's not fixed and will roam so I have to keep him on a chain. He's only dangerous to strangers or aggressive people,next best thing to having a gun!"

Comment: Guess what "Dave"? I rescued my dog from someone like you! He spent 5 years on a chain, was not neutered, and had a miserable life. His old owner claims he was a "useless guard dog". Now, he is neutered, lives inside our home as part of my family, and has a huge bark should anyone arrive. Dogs who live in the home are happier and far more likely to protect you because you are part of their "pack" and they bond with you. All you have Dave, is a fatter and healthier looking abused dog!
