Update 2/19/13 9pm: Willistown Police received word from the state game commission that the print belongs to a "large domestic animal, such as a dog." So that settles that.
Original story continues below.
A Willistown resident sent in the above photograph of an unusual animal track she found in her yard off Hillview Road.
Luisa Melo, who discovered the print, wondered if it might be from a bear or coyote, or another type of animal, and said she's found unusual droppings in her yard lately too.
Willistown Police photographed the print and sent the photo to the Pennsylvania Game Commission, she said.
