It is not easy to stop a dog from barking at their neighbours reason being that they do this out of instinct. A good way to stop a dog from barking at its neighbours is to cage it in its kennel whenever it does so. This should not be seen as a form of punishment, rather its correction. They would in term learn not to bark at their neighbours through this process which is called conditioning. This requires patience in order to bear fruits.

Maybe you should go talk to your neighbours. Bring him and make sure he see's you interacting all nice and friendly with your neighbour. He may see the neighbour as a threat. Or, you may invite your neighbour to your house. Let your dog have a good sniff and look of your neighbour, and make sure he see the nieghbour coming from and returning to his house. This would get him to understand the neighbour is friendly.

I wish I had an answer for this but will be following this thread closely. I have a great Pyrenees and they are known for their incessant barking! He barks at everything. We got him at a year old and have now had him for almost a year and have yet to decrease this. We tried the bark collar and it helps. But his NEED to bark often over rides the training from the collar and he is stubborn so has learned to ignore it.

We recently moved and our chi-weenie is having problems listen and barking at neighbors when we are outside. It is driving me crazy, I have tried everything I know but nothing is working. I have tried distracting him, ignoring him, and reinforcing good behavior but nothing is working. Any ideas?

Well, I think it has something to do with you. You just recently moved right? Maybe you would try to get some idea from Cesar Milan's ("the dog whisperer") videos. Here is one example that you might like to start with: [video=youtube] https://www.youtube.com/watch?v=2oxAgDnjk8M [/video]
I have learned so much from him. I like his show very much. He helped so many dog owners who have problems with their dogs. Can you imagine how he can lead a pack of dogs? How he can make a dog obey. Just try watching his videos and see if you can get some ideas for the problem you have.
