That is awful.
I had a dog that was aggressive with other animals too, so I totally understand your conflicts. (And for anyone who doesn't already know this, dogs DO know the difference between people and animals. We could, and did, put our hands in her mouth to pry her off an animal and be perfectly safe - which was more than you could say for our other dogs who were not animal-aggressive. She was the sweetest thing in the world to humans, never even growled at a human being.)
Is moving a possibility? If so, you do NOT need to do so in three days. That's just the time they give you before they start legal proceedings. It will take much longer - weeks or even months - for an eviction to be finalized. If you have evidence that they declined to get vet help for the sheep, it won't totally absolve you, but it's certainly in your favor.
Wishing you and your family (furry and non) a swift and happy resolution.
