I learned about prey drive when I was 4 years old, my neighbor friend had just gotten a baby rabbit. I was visiting ( just across the field, and she took it out to show me, set it on the ground, and my beloved Sheba killed it instantly, then set it back down. It didn't even look damaged, there was no gore, but our parents had to explain prey drive to us.'

It didn't mean Sheba was a bad dog, they explained, but that she had this instinct, and we should be careful to never let small animals around her.
