 A seeing-eye dog, a German Shepherd, and I've heard this now two other times. The night before a strong earthquake, the quakes over in Livermore, her dog developed convulsions, and she thought she was going to lose him. The vet couldn't see what was wrong, and then after a few hours, he was okay. The next morning, she walked out for a morning walk. She opened up the front door, and she said it was almost like opening up an oven door. I felt as if the air were layered. It felt like it had a texture to it. I don't know how to describe it, she said.
