When my son was a toddler, we lived near an alpaca farm. They had two Great Pyrenees to keep the mountain lions away. One of them took to my son and dug a tunnel under the fence to come visit him once a day like clockwork. The owner found the tunnel and fixed it, the dog dug another one.

Finally he just told us to come over and allowed us to basically visit the farm whenever so that the dog wouldn’t keep digging.

He was so gentle with my son. I never felt unsafe with that dog around.
