A stray dog has been hanging around their house for the past week. It looks bad. Like it was abused and wasn't fed. My parents gave him a blankie, water, and food. He is the most friendly dog. Not sure what breeds he is, he is obviously a mix. Today when he stood up off of his blanket my dad noticed blood on the blanket. They said it was almost like something grey with blood. I feel so sorry for him. What could it be? I've never heard of the grey before.
