I don't know if Great danes appear in more or less vids, but we should admit their videos are the most sexy and impressive, no dog or cocks like themThink it depends. For M/M you see a lot of rotties, GSD, maybe husky. For F/M (male dog topping), seems like golden retrievers, labs, and pitbulls are surprisingly popular. Great Dane idk, I've seen some but not enough to say it's that popular
