Why Does Dog Bark All of the Time?
Barking and growling serve to alert other pack or family members to danger. If your dog barks because it is startled by a noise outside and you immediately come to see what it is barking at, it will associate barking with the reward of seeing you next time it barks. Barking is sometimes a symptom of another problem-for example, fear, boredom, or stress. If you fix the problem, the symptom will likely go away.
Dogs don’t really do well alone in the yard, they are better off being with you, and the neighbors can’t complain that way. Crate him if need be. Dogs may also bark or growl when they see prey, such as squirrels, and they may bark for attention, food or if they are anxious. Dogs also bark more than their evolutionary ancestor, the wolf, which seldom barks after it is no longer a pup.
The key is to identify why the barking is occurring, and going from there. Remember, your dog just wants to please you and you just need to help him or her understand how to do that.
