She now will try to avoid the things that stimulate her to bark.If she ever starts the superfluous barking, we simply put it back on.

It starts off with a light vibration (lets the dog know, ummm better not bark again), if the dog barks again, goes up another level.

Success! It worked so quickly and is still used as an effective threat!

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.
