Riding hound

From Memory Alpha, the free Star Trek reference.

The riding hound is a Cardassian animal. A five-year-old Elim Garak once attempted to ride one repeatedly on the only day he and his father Enabran Tain ever went to the country. On his deathbed, Tain recounted the event and how he was proud of his son for not giving up. (DS9: "In Purgatory's Shadow")
