I need some advice/help. My dog (Molly) was just laying down on me and I felt some shaking. I sat up to look and it seemed like her whole body was shaking. It was more like a vibrating/trembling than a type of convulsing. It was her whole body but not her face or head, and she did not lose consciousness. It lasted for about 3 minutes. When it stopped, I offered her some food to see if she would take it and she happily ate it. I'm very nervous about what causes it or what it was! Any help would be appreciated!
