constant barking

Question
I have a aust. cattle dog (blue healer),that constantly barks all night long. Is there anything i can do to correct this behavior.  

Answer
Dogs bark out of boredom, to alert when their territory is being invaded and when communicating to other dogs. Your dog is probably doing all three.

If you have not done so already, I suggest bringing your dog inside your home when you are there, including to sleep at night. He will find it much more peaceful and so will you.
