The Appenzeller Sennenhund has a cattle dog instinct very deeply rooted in, and sometimes it can manifest itself in the fact that your dog can lightly bite children on the heels. Perhaps, in the mind of a dog, responsibility for sheep or cows is akin to responsibility for a child. By the way, the Appenzeller Mountain Dog takes this very responsibility very seriously. So serious that to protect the herd entrusted to him, and, moreover, to protect children and his family, the dog is ready to give his life.
