My retriever mix has the most frustrating neurotic habit that we haven't found a way to stop yet. She's in SAR training and loves her job, but this is the one thing stopping her from getting her certification. She is fixated with shadows, reflections and flashlights. She would chase them all day and all night if left to her own devices, and tries to dig them up, barks at them and runs up walls after them. She has to pass a night search test, but she goes insane if she sees a flashlight. She's very hyperactive and smart, which I think has a lot to do with it. Usually she listens very well and is easy to train, but when she sees a reflection she changes completely. Her tail goes straight up in the air and wags like crazy, and even if I put my hands over her eyes she is still intent on where the reflection is, and she goes completely deaf on me. It's hard to stop because I can't watch her 24/7, and often I can't control the shadows/reflections. Does anyone have any ideas? It makes me sad seeing her act like this, but I don't know how to help her without playing with her all day.
