Ultrasonic Bark Control - Did It Stop My Dog From Barking?

Ultrasonic bark control devices are making waves in the dog market today.
They are even being spoofed in the Jay Leno Show.
  More and more dog owners are realizing the importance of helping their dogs get rid of the bad habit of excessive barking.
Training without the need of hurting their pets.
These bark deterrent devices lets you have quality time with your dog.
No shouting and getting embarrassed because of your best pal's behavior.
You have control over your dog's barking habits by simply turning a switch on or off.
You don't have to worry about hurting your dog when you buy ultrasonic bark control.
It stops your dog from barking by immediately attracting their attention through emitting frequency sound waves that only dogs can hear.
These sound waves are triggered by bark sounds so you can still have your dog's attention when you want to not unless they are barking.
You won't hear the ultrasonic sounds but it will definitely be heard by your dog and will interrupt him from barking further.
The dog silencer sound will be automatically triggered by any barking sound by your dog or your neighbor's dog so I think you'll be hitting two dogs barking at the same time.
Kidding aside, when your dog barks, he is trying to tell you something.
However, it is also important for you to tell him when and where barking is not allowed especially when you are in a public place.
I am a dog owner myself.
I own a Pitbull and you probably know that Pitbull's have a reputation of barking at other animals because they are very territorial in nature.
I used to get embarrassed when I had to keep on shouting to stop "Coda" barking.
But unlike other Pitbulls, my dog grew up sweet.
My little nephews and nieces can play with her freely without me worrying about their safety.
But it becomes a different story when she sees other dogs around or sees any other animal.
Because of this I can't take her to the park and we only stay at our own house or have to go to my sister's spacious backyard so we can play.
That is why I didn't think twice buying an ultrasonic bark control device.
I knew I had to find a way to make my dog understand that excessive barking is a bad habit that we have to get rid off if we want to be able to spend more quality time together.
