remoteness simply isn't a factor whether or not they "revert" to feralness, it's their continuous exposure to humans, especially in the puppy stage. if dogs aren't accustomed to humans while they are puppies, they generally go feral. and despite what you see in glorified videos on social media, most feral dogs with pups hide their litter the best they can. feral dogs breed more feral dogs and the problem persists. dogs are clever, if they feel like they can get food from you by cozying up to you they will, but in a pack and they feel their chances are better trying to eat you, they will as well.
