The Humane Society of Southern Wisconsin is looking for anyone who recognizes this puppy, which a witness said was thrown from a bridge into the Rock River.
According to a Facebook post by the humane society, a fisherman saw a young person walk the dog to the Memorial Bridge, take off his leash and throw the dog off the bridge into the river.
The puppy swam to the river bank, and the fisherman brought the dog to the humane society.
The humane society is caring for the dog, and they suspect he may have been stolen.
If you know this puppy or have information about the incident, you are urged to contact the humane society or the Janesville Police Department.
