We adopted a six month old border collie/poodle last fall from the SPCA. He is wonderful. He comes when he is called in the house and he does all his basic training. I did take him to obedience classes. But he is over the top fixated on the chickens. I tried to introduce them slowly when we first got them and he seemed interested but nothing more. At some point over the winter he lost control. The moment we are out the door he is trying to get to the coop. He has to be on leash at all times, and if I do let him off, all he does is run circles around the coop and pen - whether the pop door is open and the girls are in the run or if they are closed up for the evening. I have been working with him to come on leash from various points in the yard. I could have sirloin tip steak ready for him, it doesn't matter. He wants to run back to the coop. The kids can't play ball with him because he totally ignores us, or he fetches the ball and then drops it and runs to the coop. I know it can be done, but how in the world do I get him to leave the chickens alone? If I let them free range he is either inside in his crate or tied up with us outside but he barks his head off. Any help would be greatly appreciated!
