The Wisconsin Department of Natural Resources, U.S. Fish and Wildlife Service and U.S. Forest Service are seeking the public’s help to solve the poisoning deaths of domestic dogs and wildlife in northern Wisconsin. A $1,000 reward was offered Thursday, April 25, by the U.S. Fish and Wildlife Service for information leading to an arrest or charges being filed in connection with the poisonings.

Since December, dog deaths have occurred in Bayfield, Marinette and Florence counties, according to a release from DNR spokeswoman Joanne Haas. The poisoning took place on public properties in the counties managed by the U.S. Forest Service and the Goodman Timber Co.

The poisonings appear to be deliberate, according to Dave Zebro, regional conservation warden with the DNR. They involve meat laced with the agricultural insecticide carbofuran that has been placed along roadways.

Investigators say the poison was found on the ground in rural areas and ingested by the dogs. Each dog died in less than 30 minutes after ingestion. Symptoms of poisoning include seizures and foaming at the mouth.

In addition to the poisoning of family pets, investigators have also found dead coyotes weasels, raccoons and one wolf they suspect were poisoned. Lab tests are underway to confirm the cause of death in the wildlife cases.

The poisoning incidents have picked up within the last month as snow has been melting, Zebro said, and the majority of cases were in Florence and Marinette counties.

People walking their pets are recommended to keep them on leashes to restrict their movements off roadways and into potential contact with any possible poison.

Anyone with information or a tip is asked to call or text the Wisconsin DNR hotline at 800-847-9367, the Service Office of Law Enforcement in Madison at 608-221-1206 or report online at
