I came home a few days ago to find one of my hens dead and my dog licking it. I presumed my dog killed it but its so out of character of her that I really could not believe it. The hen had no wounds on her. I gave the dog the benefit of the doubt. Everything returned to normal. I forgot about the incident. BIG MISTAKE. My dog is a small poodle mix dog. She has been around my chickens since she was a puppy - about 3 years ago. There has never been any problems with her and the chickens. Every day I let my hens and dog out into the garden and I go to work. The dog and hens hang out together, sleep together and are totally at ease with each other. My dog used to protect the flock from cats and predators coming into the garden. But now my dog has gone chicken crazy and is totally obsessed with killing more. I came home today and my dog did not come to giver her usual greeting. I found her behind my pond filter totally covered in mud and dirt. Water was gushing everywhere from the pipes the dog had broken and plants were ripped up and scattered about. She was trying to get to something under the filter box. My heart sank when I saw the feathers on the grass. I pulled a soaking wet, bloody hen out from under the filter box. Then my dog jumped up to grab the bird from my hands - she never tried to grab anything from me, even her food or toys. She was running around and around the run trying to get in, jumping at the wire and would not calm down or take notice of me. I had to pick her up and she tried to bite me! This is 100 per cent not my dog! She never shows aggression to me or anyone or any animal before. I shut her in the house and she ran from room to room looking for a way out and did not calm down for over an hour. I know I will never be able to let my dog anywhere near the chickens now. I clipped all the chickens wings (12 of them) to stop them flying out of the run today. But I fear my dog will eventually get into the run one day. I love my dog - and my chickens. I keep my chickens as pets. I just don't know what to do now. I don't want to give away my chickens and my relationship with my dog has been ruined. I just don't know what to do next?
