I think that my neighbor's three dogs have A.D.D. I was cleaning up the alley that runs behind all of our apartments this afternoon. When I came to the area behind her apartment, her dogs began their obligatory barking. They continued threatening me with their supposedly intimidating barking for about five or ten minutes, then they stopped. It was about five minutes later when they came back over to the fence and challenged me again. Almost like they had walked away from me to check out something else on the patio and then suddenly remembered, "Hey, aren't we supposed to be barking at that guy back there." This happened about three times while I was working back there. Wonder if they make Ritalion for dogs.
