I swear Bentley senses a ghost in my condo. Since we got him 7 weeks ago we have been living with my boyfriend but about once a week, I will go over to my condo. Everytime we are there he goes into what was my daughters room and goes crazy barking at the closet. I wonder if he senses that her dog lived in the room with her, or he senses my cat that I put down last year. I bought my condo from the daughter of a woman who passed, I don't know if she passed in the condo or not. If she did that could explain why he freaks out there. I believe that he can see or sense something that I can't.
