Our border collie has become a public nuisance with his constant barking all day long and the neighbors are starting to complain. He barks at anything that moves from cars to the wind and sometimes it seems he just barks to bark. Im looking into the anti bark collars like the ultra sonic or shock my wife wants the citronella spray one (which I don't think will work). Does anybody have any feedback on these things some are really expensive and they all have mixed reviews, so I figured I would check here for some more reviews. Also if anybody has any ideas on how to get him to stop barking that would be great.
