i know that there are people that feel assured at a barking dog. i had a neighbor that had a dog that barked 24/7. They said they never heard it bark. It was very annoying to say the least.

If my dog barks I get up to see what is happening because it doesn't bark unless it senses real danger. The UPS man can come and go and I never know it because they are best buds. If she has ever seen you in the past then you are ok and she will not bark. We have deer frequently and she will always alarm with a braying bark.

I have thought about getting a collar like The invisible fence. i hear that these are ineffective for some breeds. One of my friends had a lab that learned that he could run fast through the Fence and it only hurt once both ways. It would run out and then later in the day run back in.
