I have a 7 month old maltese/shih tzu cross. She is the most loving dog. Super in every way except barking. She has that horrible yip yip and barks at every thing and every sound. We have been to puppy classes and tried the things they have told me. Making loud noise, that lasted about a month. Next was spray with water bottle that lasted about 2 weeks. I tried quietly saying shhhhhh and immediately giving her a treat then when quiet. That lasted about 3 days. I have a bark collar that I had used on my older dog. I hate using it and she seems to know the minute you take it off. However, the neighbors are starting to complain and we do have a city barking ordience. Anyone have any tips for me???
