MADISON, Wis. -

A Dane County judge has postponed a ruling on a request to block hunters from training dogs to go after wolves until later this week.

A coalition of humane societies has filed a lawsuit challenging this fall's hunt. The group alleges the Department of Natural Resources failed to set up restrictions on the use of dogs, creating the potential for bloody wolf-dog fights.

The coalition wants Judge Peter C. Anderson to issue a temporary order blocking the DNR from issuing permits unless the agency notifies hunters they can't train dogs to go after wolves.

Anderson said during a hearing Wednesday he was still reading case law related to the lawsuit an hour before the hearing began and didn't want to rush into a decision. He said he would rule Friday.
