We've had trouble with her before. She keeps finding places to dig under the fence separating our yards, and chasing them around. However, this time was the last straw when she killed one of our neighbor's goats. My mother is paying for the goat and may be helping bury it.
Other than that, I'm not really sure what to do. I can imagine how I'd feel if one of my pets was killed by a neighbor's animal, so I feel pretty bad. Yes, I'm telling an internet forum about it, but it's still something I'd like to talk about.
