At the end of last winter, authorities on the Minnesota-side of the St. Louis River were battling a rash of dog poisoning cases that has so far gone unsolved - at least at this point.  This year, it appears to be northern Wisconsin's turn. According to news sources, law enforcement officials have been investigating a round of dog poisoning cases that started back in December.  So far, there have been dog deaths reported in Bayfield, Marinette, and Florence counties.

Officials with the Department of Natural Resources say that it appears that the poisoning took place on public properties - some managed by the United States Forest Service and others owned by the Goodman Timber Company.

In addition to the family pets, DNR officials have also found dead coyotes, weasels, raccoons, and a wolf.
