Jackson is a black Great Dane who belongs to my father-in-law. When he first joined the family ad I saw him I thought, "Why the hell did he buy a horse?" This thing is huge. And a moving disaster. He is so large he bumps into things, gets in the way and you can't get around him, demands attention and drools. He is also pretty funny and has a very real personality.
After being around this dopey dog I can see how the cartoon character Scooby-doo got its personality. These dogs are almost people at times.
