I had heard a legend about the dogs star in our night sky. This was not about Sirius but about Polaris. The story is that the council of wolves, coyote and fox each decided to send companions for the people. They became the dogs which we have as faithful friends in many homes today. The three stars of the handle in the little dipper represent the wolf, coyote and fox, while the four bucket stars represent the offspring sent to the four directions.
I don't know if this is an actual legend told by anishnabek, but I do love the story.
