Teddy's freedom...
I do enjoy having my puppy with a Halo second generation collar. We have lots of acres and she's free to run on quite a few of them, she enjoys having her freedom and for myself knowing that she's not going to leave her allowed area, when she approaches an area that she's not supposed to be in, the collar will produce a tone then a vibration and then if she continues it will zap her. But she's learned from that and knows exactly where her boundaries are, plus the accuracy of where she is at is amazing. We've had a few glitches with the system but they seem to be ironed out and again I feel good about having the system, is she is an awesome goldendoodle and I feel that she's safe and secure with the system...
