I think your dog is testing the boundaries of his territory. He's new to the area, so to speak, and not sure who's in charge and what he can get away with. He doesn't know what is safe, because he hasn't been around the condo long. He can't tell the difference between a neighbor and a burglar and your best friend. You have to tell hiim, in doggie language, how to behave. I highly recommend the book "Don't Shoot the Dog" by Karen Pryor. How to speak dog and be understood.

For what it's worth, I dislike the anti-bark collars. There are situations where barking is a good idea, such as then there is a burglar or when the living room ceiling caves in. A dog trained with a bark collar may not give the alarm in time. When my dogs bark appropriately, I praise them for it. I tell them what good little guard dogs they are, how brave, and cute, and fuzzy . . . <img src="/images/graemlins/smile.gif" alt="" />

My personal ideas are to try::

1. Dominance Downs. This is where you flip the dog onto his back and place your hand over his throat. In the wild, pack leaders do this to pack members to enforce their leadership. By telling your dog that you are the pack leader, you make it *your* territory, not his. My dog trainers recomended doing this during play sessions. It teaches them to trust you ("see how I could crush your throat but I'm not doing it?") and then continuing to play afterwards helps them bond with you. If one of the dogs gets out of line, I do it then as well, but I add the element of growling really loud.

2. It's good to establish yourself as pack leader, but don't go overboard. Being Alpha is not the answer to every situation. I like to watch my older dog's method. When it's something like a toy, or who sits on the couch, Jack lets the other dogs be as alpha as they think they are. But when Jack decides that he wants everything in the food bowl, I swear his jaws triple in size and his teeth grow razors as he announces to the other dogs, "I am the Uber Alpha!" After dinner, he is mild mannered fluffy puppy again. Pick your battles.

3. Stay calm and quiet. Yelling, to a dog, is just like barking. "If Mom is yelling then it must be time to bark, so barking was the right thing to do in that situation, good for me," he thinks. Instead, stay quiet. Walk up to him and quietly give the command to be quiet. Then bap him on the nose, and calmly go back to wherever you were before and do whatever it was you were doing as if nothing happened. Repeat as needed. When it's quiet time, everyone is quiet.
