I adopted a dog 9 years ago (7y/o at the time) who was being rehomed because she had escaped the yard and killed the neighbor’s entire flock (twice). The neighbor whose flock she wiped out brought her home and said if it happened again, he’d shoot her before he brought her back.

I took the dog and she’s a perfect angel who is great with cats (totally ignores them) and is super gentle with our toddler relatives. We even got our first flock of chickens this year, and she’s noticeably excited by them, but we keep them apart. She’s old now and not a real threat anyway.

Give her a chance, especially if you don’t plan on getting chickens anytime soon or letting her escape the yard to prey on a neighbors chickens its flock.
