I now have four little bundles of joy and recently I have been paying attention to their barks and the different "tones" of the bark. The most recent addition has this really high pitched bark and I have to confess it stands out in a not to good way. It has to be the most irritating bark of all. The other three also have their own distinct barks so that each can be identified by their barking. Have you ever paid attention to the kind of bark your dog has and isn't it something like us humans having different "voices"?
