MERRILL, WI (WTAQ) - Authorities in north central Wisconsin are looking for the person who abandoned a dog near a freeway exit in 10-below weather.

Lincoln County sheriff’s deputies are treating it as an animal abuse case.

A concerned driver found a mixed-breed dog tied to a post Monday on the Highway 51 freeway near Merrill.

Deputies took the pet to the local Humane Society. The male dog had a collar, but no tags.

Sheriff’s lieutenant Tim Fischer said the pet is in relatively good health, but it’s a bit nervous around strangers. Now, officials say he just needs a good home.
