My very first dog was a Great Dane named Nikki that I would ride around the backyard like a horse (I was three).
I don't remember specifics about her but I do recall that she was very sweet and occasionally she would share a bowl of dried dog food with me that would end up giving me a rash on my face due to it's ingredient list that mostly likely included bone and pork asshole.
Good times.
