"Yet cougars, and coyotes to an even greater extent, are far more likely than wolves to be behind the disappearance of rural pets or livestock, and are certainly far more numerous on the Washington landscape"
Very true according to WDFW, even if you saw the wolf that chewed your dog up they will ask, "are you sure it wasn't a cougar". If there's a fresh pile of wolf scat next to the new calf that was killed in the night, WDFW will spend hours "investigating" and come out with, the calf was killed by a coyote. Or if a cow and calf are killed by wolves, they will forget all about the calf and run to the news papers claiming they don't know what killed the cow but something sure did. WDFW will explain how the cow was just a pile of hide and hip bones by the time they got there. The calf will never be mentioned.
