First, you need to make sure the collar is snug.  Fitting this barking collar the right way is crucial if you want to have any success.  You do not want the collar to be too tight, obviously, because you do not want to choke your dog.  Even though you are trying to train your dog through a form of punishment you do love your pet and want him or her to be comfortable throughout the day.

Having said that if the bark collar is not tight enough its sensor will not be able to  detect your dog’s voice or vibrations and it will be useless.

Second, if you have a dog that has thick hair or a lot of hair you need to have him or her.  Hair is a another barrier to the sensor. Pugs have light hair so the anti bark collar worked great on mine.

I had a lasso dog (very boring breeds I might add, he got dumped on my by my last girlfriend/ fiance) who had a lot of hair and it almost never worked.  I had it on him for a whole week and the device never sensed his bark.

If you have a breed that has thick hair bring it to a groomer and get his or her hair cut as low as possible.

Third, you need to make sure the batteries are good.  I cannot tell you how many times people I have know, or myself, have used an anti bark collar and the batteries were dead.  The battery on the collar is small and the power runs out quick.  They usually have a light so you know if it is good or not.

On my Petsafe shock collar it would have two blinking lights as long as the battery worked.  When they were in fact dead a red light would come on.  Kind I handy I think.  Obviously, if there is no power going to the collar it is not going to work very well.  Its one of those items that should be really self explanatory but we all forget from time to time.

Follow these three items and your anti bark collar should work the way its designed.  To shut your dog up in the middle of the day!
