I can't remember much about it but I am looking for a science fiction story about a woman who is camping or something similar on a planet that has been marked as having no sentient beings living on it. She encounters a dog like creature who can communicate using telepathy and can move things using telekinesis. She calls it Onyx as it is black in colour, and she tries to take it to someone as proof that there are sentient beings on the planet.
Unfortunately I can not remember when I read it, can't even tell you if it was in the last 10 years or 20 years... I know it was a book, but more than that I have no idea.
