I once took a cruise on a ship which had a "resident magician" who used two small poodles in his act. He was on a vacation home at the time, but had left his dogs on the ship because they would otherwise have been subject to quarantine when he debarked in Europe. The ship had a square, raised, grassy area on the bow deck to which the cruise director or one of his assistants walked the dogs 3 or 4 times a day. The dogs were very cute and passengers who saw them seemed to be amused by the idea.
