I have a very strong headed German Shepard puppy (about to be 1 year). I was at the end of my tolerance with him. I had even sent him to 7 weeks of training where they had him walking in public without a leash. But as soon as he got home, he remembered he was in charge here and back to not listening and doing what he wanted.

Bottom line is this is a great collar!

For all those out there not satisfied with all the collars out there, try this one. I was suspicious and didn't think it would work any better than all the others. I was pleasantly surprised.

I really like this collar. It actually works farther than 2 feet from the dog. I think I've used it about 40-50 feet away. I've only used the beep and vibrate on the collar. My dog responds very quickly and it doesn't hurt him. Since it doesn't need the probes to push onto his neck, it's very comfortable for him and he doesn't mind when he gets it put on in the morning.

I am planning on purchasing a second collar to use in training my smaller dog,Thanks for the great support.

I have been using this collar to train my dog. I have found that having the three levels of correction (sound, vibration, shock) is the best way to train the dog. I can just send a sound and my dog will respond to it quickly. The training has happened a lot faster using this collar then without the collar.
