Hi, My wife and I recently acquired 2 lovely little jacks due to a death in the family. We have had a pet jack Russell before so knowing needs of the dogs was easy. The problem we are having is both dogs are around 10 years old one male one female, the female dog barks A LOT. Does any one have a humane way to stop this. Thanks in advance Hopefully we can teach a old dog a new trick. ps They are both very happy and she always barked before we had them.
