The last week or so Sisse has started these marathon barking sessions when anything "new" has been brought into the house or if something is out of place. She just goes crazy until we either put it away or put it back where it belongs. I have tried "introducing" her to the errant item, letting her just go ahead and bark at it until she gets tired or taking her to another room until she calms down. Then I let her go back and she acts startled and starts the barking all over again. I don't mean just once in a while either, it's all the time. We can't bring groceries in, move a plant, put shoes somewhere else, Lisa can't put her bookbag on the couch etc.....what's up with her?? Does anyone else have this problem and how do we get her to knock it off??
