I think there was a Dog Whisperer episode on something similar. I think that dog had separation anxiety, but it was a barking / condo issue. Cesar had the woman exercise the dog vigorously before she left for work, and that helped.
Other than that... I read about one trainer who taught the dog that when a "flag" was in place, like a red ribbon tied around the door knob, the dog was not to bark. Again, not a perfect analogy, because this dog was barking to be let out. I believe it's instinctive for a dog to let out at least a few barks if he hears "intruders", so I would imagine it's difficult to completely stop. Good luck! Let us know how it works out. |
