Interesting. We have a dane in our neighborhood that has a mink appearance to it coat. He's so beautiful!
My mother raised two danes, one when she was in her 30's, and one she retrieved from an animal shelter when she was in her 60's. Shane was under 2 years when she brought him home. He had been kept in a very small chicken coop and kids were poking him with sticks thru the coop. Needless to say he didn't do well with children. But my daughter at the time was about 6 years old when she would stay with my mom. She was the only child he would not growl at.
The hardest part for me is that danes done live very much longer than 8-9 years due to inner breeding, they have a small heart.
