What does it mean if a dog is panting and shaking? How do you care for it?
If a dog is panting and trembling, it means that they're anxious and/or terrified. You should back off, remove the source of stress, and help doggie feel better.Stress Signs in DogsSigns of AnxietyWhen anxiety strikes your poochSigns of Stress ChecklistThere could also be a medical reason, if you have reason to presume that doggie is not very stressed emotionally: Dog Shivering or Trembling: Causes and Treatments
Can dogs sense a ghost or paranormal presence?
The possibility is extremely slim and honestly I don't think so. Dog's sometimes bark for no reason at all or because they hear very subtle noises outside and "think" someone is coming. But I have heard dogs having a special sense. I know before a earthquake in Peru my mothers dog apparently 30 minutes before it happened had been walking around in circles the entire time and whimpering before the earthquake hit. Dogs do feel things and its hard for other people to understand including me. But if you really believe that he sensed your other dog then he might have. But trying to convince people on the internet of a barking dog isn't exactly going to make people believe. If you believe it, that's all that matters.
