I have had chickens for years & a very good chicken-guarder Pyrenees who is now aging. She has never killed any of our chickens in the 9 years we have had her. We now have a 5 month old puppy pyr who we are trying to train around the chickens. The process is going very well until recently. We have neighbors behind us who have chickens & their chickens are flying over the fence & our two dogs (even the chicken safe one) have decided it is quite a sport to kill them together. We have talked with the neighbors for years to get them to keep their birds on their property but they have yet to do anything. Is this going to ruin my puppy?!!!! I trust that my adult pyre won't start to kill our chickens, she clearly knows that she doesn't touch our chickens, even now. What can I do? Any suggestions? I am not one to tie a chicken around the neck, kind of thing...this dog is inside & outside...I am not about to live with a dead chicken in the house, LOL!
