I just bought the coyote decoy by Edge (yote' coyote is the name) from bass pro ($65 I think)
These work awesome. Its on a stake and the wind blows it around making the body move like its walking. The tail is fur too and it moves. I place it in the field on the highest point in the wide open sometimes 100-200 yards from me. Then put my rabbit decoy close to me.
I've had two coyotes now come out into the field, starring at the coyote decoy but angling towards me coming to the sound, not taking its eyes off the coyote decoy. I could do jumping jacks while they were getting closer, they had no idea I was there.
