Hello I have had my dog fo 4 years. Just two days ago she started acting very strange. When I woke up on Monday morning she was curled up in a corner whinning. She acted like something had scared her to death. She never comes up the stairs to the bedrooms latley she has been running up the staires crawling under the beds. This morning as i was getting dressed for work she ran into the bathroom and went into the closet. My husband says maybe we have a ghost that scared her. She is a miniture schnauzer she still eating she dosent bark at anything anymore, and as you know this breed is a barker. I need some advice please help!!!!!
