OK, so I took advice from previous posts. Chloe, 6 mos, is now always in the house or tied on a 20 ft. line. She is sometimes tied near the heifer pen during chore time, but we never take her near the cows. Time is in short supply around here right now, however, we try to play, on leash, each day, and I get in obedience time whenever I can, which is not as often as it should be. Two BIG problems: incessant barking, and not coming to any of us when called. She has escaped the leash three times in the last 2 days. Today she lunged hard enough to break the leather collar. On the first escape, I was working in the yard, she would come just close enough, and then dash away before I could grab her, or even touch her. I figured I would let her run for a while, she stayed close, and after a bit came close enought to be petted and then CAUGHT! The escape this am, she did the same thing, coming close before racing away. Her mistake, going into the corncrib, where Ron went on one side, I on the other, and she was trapped. The third escape, which broke her collar, left her running around during chores. She stayed quiet for much of the time, but soon started the barking and wanting to nip at heels and chase, paying no attention to me at all. By now my fuse was starting to get pretty short. When the kids came home, they chased until she got tired,(she was too smart to go into the corncrib again) and then pounced. Since we no longer have a collar, she must spend the day locked in the lvstk trailer tomorrow. I have friends who let their BCs run loose all day but are contained at night. The dogs always come when called. Chloe always came when she was younger, but suddenly decided it was not the cool thing to do anymore. I am doing my best to be patient and react quietly, without yelling, but I am near my wits end. HELP!
