Relieved there were no photos in your post, Brigid! I think your anger is pretty rational, actually.
Yeah, I don't take photos. We have security cameras up and I asked the Mr. to wipe the footage. The mental images are enough.
Dogs don't think like we do and she's probably forgotten all about it. She doesn't know that I've spent the last three years advocating for her and so far have been repaid by her biting me, and biting my kids but I kept trying to help her. When I went outside she put her tail between her legs to slink into the house, but that could have been as much because she's an anxious dog imposter, not because she knew that she'd done something bad.
Even knowing it's irrational, I'm still furious at her and this was the last straw.
The chickens are all fine. The hid together in the husband's garden.
Unlike wild canids, domesticated dogs kill for the lulz. That's hard when they've enjoyed other pets or livestock we depend on.
Yup. The absolute carnage that wiped out half my chickens and had me chasing three geese and a duck along the highway was most likely someone's dog. I was in the woods half a mile from my house for an hour and a half chasing a goose (and stupidly ran into the road to keep her from getting hit). Parked on a neighbor's yard and his father was screaming at me until I walked out of the woods with a bird. Derailing, but some helpful fuckwit decided to "help" me, didn't listen to a word I said, chased her farther into the woods, and then said

maybe she'll find her way home.
I am so done with dogs. So. so. so. done.
ETA: after the carnage the chickens got a run and everyone is penned 90% of the time. They were out yesterday because I was home doing chores.
