OMG ! Kathryn v, I know what you are going through! Remy has that high pitched bark too.I tried the automatic spray collar but her bark wouldnt make it spray so I switched to the spray collar with the remote control and that has done an amazing job of controlling her barking rampages. Yes I do have to stand there and hit the button on the remote when she starts to bark but I am there supervising her anyways so its not a big deal. When she wears the collar now she doesnt bark at all (she is six months old) It may still take some months of wearing the collar to get her totally reliable in being quiet but at least now I have my sanity.
