I have never had a problem with my dog she is trained very wel and never touched any of my chickens over the years she even protects them from outside critters. Today I look outside and she is dragging one of them through the yard and shook her .. it’s awful I have no idea what started this. She has no blood but is keeping her self stiff and not doing anything. How likely will she make it through the night after being shook like that ? And has anyone have their dog turn on the chickens after years ?
