Kennedy and one of his dogs, Splash, wrote a book together, "My Senator and me." Check out an audio clip of Kennedy reading the 2006 book here.
Kennedy and his dogs Splash, Sunny, and Cappy were often seen together in the Capitol building, and water bowls and tennis balls were a staple on his office floor. Some said that the presence of the dogs helped to cool tempers during difficult negotiations--we sure know how to break the ice! The dogs were even known to dig in the garden outside of the Russell Senate Office Building. Even Kennedy dogs misbehave sometimes!
Check out this article from Politico.com about some more ways that Kennedy's dogs lightened the mood on Capitol Hill. The saying goes, "If you want a friend in Washington, get a dog." But it sounds like Teddy had plenty of two legged friends too. I am sure the dogs will be missed up there, but I am sure these guys miss their #1 person too.
