Abbey Carlson and Thomas Fishinger were arrested after they allegedly transported Carlson's 10-year-old daughter inside a dog cage in the back of a pickup truck on Monday.
Fishinger claimed the girl wanted to ride in the cage with the family dog while driving back from his mother’s house.
Motorists called the state police with the license number of the truck on the Pennsylvania Turnpike. State police then called authorities in Millvale, Pennsylvania, who went to the couple's home and arrested them.
According to the Pittsburgh Tribune, the couple was charged with endangering the welfare of a child.
