These collars have two sensors on them.  They sense sound and vibration and know when your dog is barking out of control.

The “Petsafe Dog Bark Control Collar” comes stocked with a Temperament Learning System which makes these anti bark collars able to work across different breeds of dogs.

Keep in mind that there are two models available depending on which size dog you have.

There is the “PetSafe Deluxe Little Dog Bark Control Collar” and the “PetSafe Big Dog Bark Control Collar.”

The models are virtually the same but one is for smaller dogs while the other is for the more larger breeds.

One would be excellent for use dogs the size of pugs and terriers.  The one is good for dogs the size of golden retrievers (those breeds do not bark that much though) or German shepherds.

Petco makes excellent anti bark collars that train your dog not to bark by the use of zapping, or shocking, him or her when the barking gets to become excessive.

The sensors are wonderful at detecting whether your dog is barking loud or if he just barks a couple times.

Keep in mind that dogs are smarter than we give them credit for.  I found that my two dogs learned that the device would only go off after at least three very loud barks.  So they learned to bark just two times and quickly shut their trap.  I’m okay with that.

If me and my wife are at sleep, during night, and someone is trying to break into my home all I need is two barks to warn me.  Otherwise, in the middle of the day, I do not need my dogs to tell me every time someone passes by my house.

Petco Dog Bark Control Collars are a great buy.  You can usually get them for around $100.  A definite must buy if you want a little peace and quiet. Petsmart has every sort of collar you could want and as far as I know they are offering $5.99 flat rate shipping on orders of $60 or more

I would like to assure you they are not.  The shock produced by these collars are really not meant to hurt the dog.  The shock is meant to create a small unpleasant sensation that tells them to stop doing whatever they are doing.

I was fairly leery myself of the whole “shock collar” device until I got a pug two years ago.  He is the cutest dog you have ever seen but he will bark non-stop at any and everything.  A school bus, kids, the mailman, other dogs, you name it he barks at it.  It was enough to make your nerves rattle at times.  I had to find some way to address this problem.

I went to the nearby pet store, Petco, and bought an anti bark collar for approximately $100 after some fierce negotiating with the store manager.  They had an ad on their website for one price yet when I went into the store they had another price.  The difference was $30 so I got them to take that off.  Anyway I bought it and put it on my dog that very day.  No keep in mind that most bark collars have several levels of correction so you can choose how strong the shock will be.  Even the top level will not hurt your dog but for small dogs likes mine I keep it at medium.

I have to admit that I did feel bad at first but wow did the training go fast.  With the collar one my dog stopped the constant barking within several hours and stopped most random barking within 2 days.

The bark collar does not just zap the dog whenever he barks.  He has to bark loud and more than three times for it to go off.  So after a while if he barked it was only two times and then he abruptly stopped.  Dogs learn quickly!

My pug is pretty good about barking now.  I do not mind the occasional bark he and there or to alert us that someone is at the door but the out of control inappropriate barking is pretty rare now.
