1.   I have known cases where dogs have nipped babies.

2.   My child is allergic to having an uncontrolled dog nip him and jump all over the place.

3.   This can save you a lot of trouble if your dog nips someone in another state.

4.   Just down the way, five cows lay dead in a grazing patch, and a dog nips at the fresh meat exposed in the foggy air.
