Dogs and Prey Animals

My dog doesn't prey on other animals. She is somewhat afraid of other animals. I think it's because most of them are bigger than her.

My sister's dog is another story. Her dog is usually very gentle. But, don't let any other animal get in the yard. She will chase after them, corner them, and kill them. Last year, at a family party, she killed a squirrel that made the mistake of getting in her territory. She has killed rats before, too.
