A camping outing at the Susquehanna State Park became a nightmare when one of Cathianna Rosenthal’s dogs named ‘Knox’ disappeared. The odds against finding Knox were great. Afterall, the Susquehanna State Park is made up of more than 2,700 acres of heavily-wooded terrain. Fortunately, Knox had just learned how to swim. #goodnews #dogsswimming #susquehannariver #dog #dogsofinstagram #instadog #dogs #dognews #lostdog
