I might of had share this one story before but since we are on the topic of ghost and dog I'll post it again.
In the early 2000, one of my uncle had his giant German Shepherd tied up on a big tree inside a fence cage on his front yard. One morning my aunt was leaving for work and notice their dog swinging on their kids' swing located on the left side of their house, she thought it was strange but didn't think much of it and hurry off to work. She phone my uncle to tied up the dog, that maybe it had gotten loose somehow. It happened again a few weeks later, this time she got a little goose bump chill and went to wake up my uncle to go put the dog back in it's cage. The dog was actually swinging like a person would, pulling back to go higher and than leaning forward when falling backward. They didn't tell anyone about the weird occasion until other strange stuff started happening, they called upon a shaman to investigate. Turn out their yard is haunted (not their house), and the dog they saw swinging is not their dog, it was something transform into it and hide their dog. My uncle didn't understand why his dog couldn't do anything or why those ghost wasn't scare of it. The shaman said that ghost and demon are only afraid of dogs with eye dot on top of each eye like the Doberman. The last time I was at his house, he had about 10 little miniature pincher. Crazy world we living in.
