WOLF-DOG HYBRID CASES IN WISCONSIN.

Fourteen cases of free-roaming wolf-dog hybrid incidents involving Wisconsin DNR or USDA-APHIS occurred between July 1989 and February 1998. These cases involved 33 different animals, including 14 wolf-dog hybrids that were shot, 1 accidentally killed (vehicle collisions), 9 live-captured and placed in captivity, and 9 disappeared or remained in the wild.

Livestock were verified killed/attacked by one group of hybrids in 1989, and possible depredation by a wolf-dog hybrid occurred in 1997. A wolf-dog hybrid was known to be free-roaming on a farm that had 9 calves killed and 21 missing. Although some calves were verified as probably killed by wolves, the presence of the wolf-dog hybrid complicated investigation/verification of losses.

Wolf-dog hybrids challenged dogs or humans in 5 cases, including 1 case of a hybrid biting a child. In at least two cases, female wolf-dog hybrids apparently bred with dogs, and one produced a pup in captivity.

Although most wolf-dog hybrids did not cause serious problems, the lack of fear of people and their pets posed real concerns. Agency dealings with wolf-dog hybrids consumed time and expense that could have been spent on wolf conservation. Calls and reports of wolf-like animals initiated investigations by WDNR or APHIS and sometime involved lengthy attempts at live-capturing. Because of concerns for protecting wild wolves, control actions have been applied very carefully. Once wolf populations are more secure, more liberal controls can be applied toward wolf-like animals that lack fear of people and occur in residential and farmland areas4.
