I used to have a beagle/greyhound mix with one ear up and one ear down. When Lacey walked around the bed, all we could see was the one up ear, it looked like a periscope! My husband used to say that we had the one and only member of the Periscope breed, and she would win best in show at Westminster!
Seriously, I'm rooting for dachsunds, shih tzus, shelties...... I guess all of them!
