Does anyone have experience with their yorkie barking uncontrollably at pet birds? My yorkie, Bailey, never noticed my parents birds (for approx. 2 years) and then all of a sudden...everytime she is at their house, that is all she focuses on. Barking uncontrollably, jumping up & kicking their cages. We have tried telling her NO!, ignoring her, even barricading the area where the cages are...any suggestions?
