I knew someone who had a dog named Tipper. He named it while it was facing away from him.
My now-deceased Father's favorite dog was named B!tch. My Uncle had a dog named "JFK". My maternal Grandmother had one named "FDR".
I don't have a dog right now, but if I acquire one in the future, I would never disgrace it by naming it "Obama".
As a side note, my sister once adopted a 3-legged stray she named "Lucky".
