Most are shock collars. But there is one that just makes a loud noise that they don't like.
My dogs - 3 German Shephards - used to raise cain in parking lots when someone walked by. I put that collar on the dash - when they barked it made that noise.

It took 2 days.

I saved the shocking collar for the wife.

 

do you recall were you got the collar? for your dogs and for the wife! could be a two fer.

 

Personally, I prefer to teach them when to bark.. or more specifically when not to bark, or to shut up on command. I liike the idea of my Dog Barking at someone at the door. Let's that person outside know that there's a big dog on the other side of that door.

Good ways to teach:

a metal can with a handful of pennies. shake it when they bark. Talk about making some noise!

Good ole News paper rolled up and a pop across the nose.

Swift kick to the arse.

All of these followed by a deep stern voice.

But when someone comes knocking at the door, tell the dog to "get 'em" that way they know when it's ok to bark.

Lots of Bad Guys depend on this training method and will carry a rolled up newspaper to swat a dog. The dog doesn't care if it's the bad guy or the owner who's swatting him. Training takes over and he goes back to his corner to nurse a hurt muzzle.

Years ago I had a Wolf/German-Sheppard mix. She was leashed and we were walking down a street in civilization. A guy walked by her and swatted her on the nose with his newspaper as we walked buy. Granted it was a light swat but a swat none-the-less

It was all I could do to restrain that dog from tearing that guys arm off. It was all I could do to keep myself from dropping the leash. But the fact was that she didn't cower. She was a great dog, she knew who to bite and who not to bite and fiercely loyal to my family. That's my definition of a great dog.

Some people are just idiots...

 

I also prefer to train them when to bark and not. Barking at the correct time with praise and/or a doggie biscuit, a command voice of "no bark" at the incorrect times. My Jack Russell terrorists have done well with this training.

I agree with LEVE on the use of a newspaper.

Some professional obedience trainers may suggest other methods.

Barring that, and you don't want any barking at all, there are "no-shock" collars out there that will release an unpleasant scent (to dogs, such as lemon) when the dog barks. My veterinarian wife prefers this collar to the shock collars. Do a Google search.

Best of luck.

 

take the time to train the dog not to bark instead of looking for the shortcut........look at it this way.....would you put that collar on a 5 yr. old to teach then to talk at the right momment?

there are tons of books and web sites that are geared towards training a dog to do anything
