Dog Health Questions: Dog barking help?

i got my dog almost 3years ago. she had really bad seperation axiety for a long time. she has since gotten a lot better. she no longer cries/barks in the kennel and can be left home alone for short periods (less than 3hours) without supervision. i have her in dog training but its more for the basics (sit/stay etc) the only problem she really has now that annoys me to no end is when people come over and knock on the door and come in. she barks for about 30 seconds-1min like im getting ax murdered. she will even bark with me standing right in front of her and i knock on the wall....all the people that come she knows. she will bark from the kennel, she will bark thru the bark collar, she will bark even if we prepare her that someone is coming (like opening the door a crack.) nothing i have done in 3years helps. any suggestions?

A Guide To Your Dog Training for Law Enforcement

Recommended Answer:
Learn how to work with a reactive dog (that's what you have). Your training instructor should be able to help you with this and any other issues your dog may have. If not, you may want to find someone more qualified. You may want to check out this website for fearful dogs (fearful and reactive dogs often have the same types of behaviors and both can be managed similarly). It has a wealth of information and links, recommended reading, etc.
And lose the bark collar - it's probably doing more harm than good.
Best wishes.

Dog Training Methods

• Watche the dog whisperer! I have the same problem with my dog and his suggestion and he even showed with a dog, is to put your dog on a leash. Have someone come to you front door and ring the doorbell. Open the door with your dog on a leash and let them smell the person until they get bored. Then go about what you were doing. Do this every time and your dog will start to realize that you are in charge. It's okay for them to bark once or twice but then should know to stop. Good luck!
