Whoa, I came late to this thread... so sorry for your loss. We had an Aussie/Lab who would catch our chickens and literally lick the feathers off their backs, but didn't kill them before we could get to them and put them back. A low level "shock" collar trained him to leave the birdies alone (we only really ever needed the BEEP). We have a Cavalier Spaniel who is a born and bred birder, but the chickens are thankfully bigger than her so she just helps herd our escapees and they laugh when she tries to bite them. Then there is our German/Aussie Shepherd mix (Luna)... yeah. She ate all poultry who left their enclosure. And it was always our favorite hand-raised babies who wanted to be with us and came out to see us. There were lots of tears. She caught and killed Kevin, our hand-raised peacock. More tears. And I would roll her over, scruff her, and look her in the eye and tell her what a bad dog she was. But then she looked at me with her beautiful brown eyes and said to me (telepathically) "mom, I'm sorry, I know what I did was wrong... I but I don't know why it was wrong!" She was right. She couldn't help it. So we made higher fences, added net across the top, and clipped our birdies. I tell my flock I can protect them if they stay home... if they come out, you're on your own. We are the only farm in our town who has not lost poultry to predators; our dogs keep them away. But I can't protect them from their protectors. Side note, after Luna turned two (and with more training) she will still eat a rogue chicken if I'm not there to call her off, but mostly she helps herd rogues back into the enclosure. Side side note: Luna has Husky in her. We had two female Husky mixes for years... I will never have another. They are loyal and beautiful, but they are asses with other dogs. They aren't birders by nature, they'd rather run, but they will kill things. Too close to wolves. We found out the hard way that you get a two-for-one bill at the emergency vet when two dogs from one family try to kill each other. And our friend found out the hard way that you don't throw a hambone in the middle of dogs on a camping trip "to see what happens." The huskies took out his pit-bulls hands down and he ended up with a torn up hand. I agree with everyone else... it's not the dogs' fault. It never gets easier to lose a loved birdie... but we love our furry babies too. We as humans have to problem solve and come up with ways to guide our pets and help integrate their instincts into our lives. Hugs!
