SCP- -1

SCP- -1 is a unique SCP as it only materialises at a certain time on a certain day each year also known as
the dead dog it was found in a family home in a small town.
The strange dog can only speak English (and bark) and has no knowledge of its origin.
On the day that the dog appeared scientists had been waiting a month before it and had been on shifts ever since as the date was not recorded.

When subjects were sent into see the dog they had a list of the questions to read.
When the subjects got to the question do you come on this day every year?
the dog disappears and any living or electrical thing or device that knows about it will forget the day it happened in a span of 5-30 days.
The only proof that were recorded were pictures found on the site of the dog and subjects say that the pictures look like the dog.
The images will go under further investigation before released to the public.
