She has become completely obsessed with staring at her shadow. It started with the reflection of the remote on the wall making her keep looking at the wall. Down in the BorKade she would go under the pinball machines and look for reflections against the wall. Now she just spends a lot of her free time staring at her shadow. She then gets mad when the shadow of her head moves. It goes on for hours. We have tried explaining it to her, but no luck. It seems that it is a problem with some dogs and is really hard to break without putting her on puppy prozac.
