From this story on jsonline.com:
A lawsuit to prevent the use of dogs to hunt or trail wolves in Wisconsin has succeeded until at least Dec. 20, the date Judge Peter Anderson will hold the next hearing in the case. As the result, the Wisconsin Department of Natural Resources issued a statement Thursday alerting wolf hunters that "the season will proceed but without the use of dogs." The wolf hunting and trapping season is scheduled to begin Oct. 15. The use of dogs to pursue wolves had been authorized by state statute to begin Nov. 26. Groups and individuals filed a lawsuit against the DNR in August, claiming the department did not have adequate rules in place to prevent potentially deadly exchanges between wolves and dogs.
