 I'm Emmylou Harris. Keeping a dog on a chain or in a pen is about the worst thing a person can ever do to him. It goes against everything a dog is. Social, a pack animal, eager to please. Chaining a dog hurts his body and his mind. It's actually a form of animal abuse. A terrible punishment for just being born. Please look out for any dog penned or chained. Talk to people about how to keep a dog inside. Make him part of the family. Everyone will be happier. Thank you for being a dog's best friend.
