Hi, I have had a small backyard flock of about 15 mixed breed chickens for about 5 years and I acquired a livestock guardian dog about a year ago after losing a bunch of birds to hawks. They have a coop and a large scratch yard and during the afternoon, I let them out with my LGD, Daisy, who has been great with them up until yesterday. For some unknown reason she attacked and killed all but one of them yesterday afternoon while I was away for a couple hours. The one that I found was alive just laying in the yard next to all of her coopmate's bodies. She is ripped up pretty bad though. Her fat layer is exposed on her back and she has several bite holes along her back. I rinsed her back immediately with iodine and sprayed her with antiseptic and wrapped her up in a towel and put her in my warmest room. She is alive but dies not look well. She is kind of wheezing when she breathes and her head is hanging low and her comb is reddish purple. I am so upset and feel so guilty. I really am at a loss for words of what happened with my dog. It's like she snapped. I left the house for 3 hours and she was quietly laying with the birds like she always did. Before I cleaned her up. The blue color is bluekote which we sprayed after we washed her with iodine initially and then this afternoon I debrided her back better and cut feathers. She seemed "okay" and I mean okay in the worst term possible but after I cleaned her she started the breathing hard. I kept her away from water and food last night when I found her because her crop was full. She pooped last night, too. After cleaning today... Covered it with vetricyn and neosporin Any help or thoughts would be so greatly appreciated.
