Training Solution. The Boxer makes for a very good watch dog. It is wise to not dismiss barking in the case that your dog may be displaying correct behavior in attempting to warn you. If you quiet your dog down each time he tries to warn you, this may backfire.
If your dog eventually learns that barking to warn you is un-wanted behavior, you may find yourself with a silent dog while an unwanted "guest" is breaking into your home. Appreciate this type of bark.
When your Boxer barks, take a look around the home and outside. If there is indeed a stranger walking by or on your property, even if it is the neighbor retrieving something from your yard, let your dog know that you appreciate the warning. A quick pat and a "good dog" will instill your approval that the warning bark was welcomed.
If you see no danger and there is not a valid reason for the barking, you should then train your dog to quiet down. They may be barking because of a car alarm 6 blocks down or a bird 500 feet away.
Your dog can be taught that this type of barking is not appropriate. It is important that you do so in a calm manner. When an owner yells or becomes frustrated, this simply makes the puppy
or dog think that their human family member agrees with the barking and is making a commotion also!
It is your actions and reactions that will show your Boxer that their barking is unwarranted. This is done by gently patting him or her; not in a reward action, but in a calming motion.
The tone of your voice must be calm and relaxed, as you give your Boxer a pre-planned command word. The most common and effective word is "Shh" or "Calm Down". The command should be short. Dogs only pay attention to the first syllable of words. If you make your command a long sentence, you will confuse your Boxer and be speaking to no one.
Self protection barking will ensue when a dog feels that his belongings are in danger. A dog can become very attached to his toys, dog bed, blankets or other objects that he uses daily.
Your dog's things should not be rearranged or bothered with, other than to clean them. A Boxer will also become protective of his food and water. The eating area should quiet and out of the way of foot traffic.
