Jackalwere
Jackalweres are one of the two most prominent examples of "antherion" (therianthropes with the base form of an intelligent animal) in Dungeons & Dragons, with the other being the wolfwere - in fact, the wolfwere has actually fallen away in popularity over the years, whilst the jackalwere has only grown increasingly prominent over the editions.
The jackalwere's "lycanthrope" counterpart, the werejackal, is an obscure monster native to the Demiplane of Dread.
