I have been trying to find a story that was read 20-25 years ago in a science fiction anthology. In the story, a big game hunter has come to a planet to hunt the most dangerous game. He goes to a bar to hire a guide. There is a trophy of the animal over the bar, a small wormlike creature. What makes it so dangerous is the fact that it is normally shape shifted into a large lion like creature that lives in packs. The hunter hires a guide who takes him out and over the course of the hunt tells him stories about the creature and other things. The hunter realizes that the creature he is hunting is actually highly intelligent and telepathic and if rejected by his pride will end up dying of loneliness. Unless it ends up shapeshifting into another form and forming other telepathic bonds. He also realizes that his guide is one of the creatures that has done just this.
