More on the ghost dog in the Ice Tower

I found out some more details about the ghost dog in the Ice Tower this week. The student who had the experience told my friend Elaine that it happened last year while she was visiting the castle with some friends. She went up into the Ice Tower ahead of them on her own.They came running up the stairs when she started screaming. She was shouting, "Get it off me! Get it off me!" When the friends rushed into the Ice Tower room they asked her, "Get what off you?" She said it was something warm pressing on her leg, like a dog. I wonder if it is the same dog which other people have felt pressing against their leg, like the visitor in the Library, or the room steward in the Slate Bedroom? Perhaps it wanders around and chooses people at random to lean on! I wonder if anyone else has had a similar experience there? Please let me know if you have felt a dog leaning on you at Penrhyn or if you have heard of anyone else who has. Thanks.
