I would suggest speaking to a professional, who can come to your home to see and assess the behavior, otherwise there’s too much guesswork involved. And it will likely require some specialist knowledge and training to correct.
Constant barking can be irritating, but you won’t be able to correct the dog behavior problem if you are frustrated. Animals don’t follow unbalanced leaders. In fact, your dog will mirror your energy. If you’re frustrated, he will be, too! And barking is a great release for frustrated energy. Take a moment to curb your own internal barking first.
Matthijs B.H. Schilder and Joanne A.M. van der Borg studied behavioral effects of electric shock collars and came to the conclusion that shocked dogs showed more stress-related behavior than the control dogs — dogs controlled via human discipline instead of no-bark collars — the shocked dogs connected their handlers with getting shocks, and may even connect orders given by their handlers with getting shocked. What does this mean? Schilder and Borg conclude that, while they have not proven that the long-term welfare of the shocked dogs is affected, it is clearly under serious threat.
“Debarking,” or cordectomy is an elective surgical procedure involving partial removal of a dog’s vocal cords. Debarking does not take away the dog’s ability to bark – it just makes it sound quieter and raspy (considered annoying by some). In this dog lover’s opinion, debarking surgery is unnecessary and unfair to the dog. Surgery and anesthesia are always risks, so any procedure that is purely for human convenience and does not medically benefit the patient or animal community should be avoided. In addition, excessive barking indicates an underlying issue that is usually behavioral. Surgery takes the noise away, but the anxiety, fear or similar problem remains unaddressed. Rather than debarking your dog, spend your time and money on training and/or visiting a veterinary behaviorist.
So if it is agreed that the most common motivations for dog barking (Separation and Defensive/Territorial) can or do occur when you are not there, what methods will stop dog barking more effectively than others? Chastising and physical punishment are obviously impossible when you are not there.
I like the place command, as it’s so nice to have them go to a place out of the way and lie down if you need to answer the door. You can find step-by-step instructions on training the place command here.
Rule out medical problems. Sometimes barking is your dog’s way of indicating to you that she is injured or sick. If there is a chance that your dog might have some medical problem or injury, you should take her to see a vet as soon as possible.
Is your dog barking over and over again at the same object, person, situation, or place? Then you need to step up and claim that stimulus as your own. Use your body, your mind, and your calm-assertive energy to create an invisible wall that your dog is not allowed to cross. Do it with 100% dedication and focus, and the results may surprise you.
Some dogs bark excessively in a repetitive way, like a broken record. These dogs often move repetitively as well. For example, a dog who’s compulsively barking might run back and forth along the fence in his yard or pace in his home.
Use training methods. Teaching your dog the “quiet” command is an excellent training technique. It will be useful for any kind of problem barking, though it may be the only option for certain behavioral problems like territorial alarm barking.
