I have a toddler, and a 14 year old dog I've had since she was a puppy. She doesn't like kids. She doesn't like my kid. But if he wanders off, she keeps an eye on him. I have a few acres of land, and now that he's 2, my boy can actually get lost. I've learned that if we lose track of him, we don't call for him, we call the dog. She comes to us when called, knows where he is, and will lead us there.
