A dog we had from a 6 week pup, became hugely attached to our older rescue dog. After years together, the older dog got to the end of the road and I phoned the vet to come and PTS at home. Before vet arrived, younger dog was taken out of the way for a long walk. When DS and dog arrived home, the the old dog was already buried on our land, several hundred yards from the house. Younger dog ran straight to the grave and lay down on it crying. He clearly knew she was dead.
Two years later, dog and I were alone in the house when he started weirdly howling and barking ; feet up at the window sill staring out, all his hair on end, wildly excited. I came to see who was arriving ; nobody. Three yards from the window in her lifelong "guarding my family" spot, stood the dead dog looking at us. In broad daylight. There was absolutely no doubt that younger dog saw her too.
As howling dog and I watched she turned and slowly walked away, and disappeared (front end first followed by back end) as if passing through an invisible screen. I opened the door and dog raced out frantically searching for her.
