Wolf/Dog no doubt, could have escaped. Have you posted on any local social media pages? Them things are legal but highly regulated, they have to have at least 10 foot fence and so far under the ground cemented in and so may square feet to roam, I've got a friend in TN with several of them and i can just about bet that is a wolf dog! Theyre usually 50-75% wolf and rest husky or Shepard!
