I'm actually a little afraid of Great Danes because my parents had one that went after me when I was playing tug of war. Danes sometimes get strange as they get older, and I figured it was a combination of previous abuse (he was adopted) and poor husbandry. But since then most Danes I've met have been sweeties, so I'm less afraid of them. Goes to show that any one breed can cause a bad experience, but you shouldn't judge the whole breed by it.
