First of all: What's the story behind this SCP? These days, SCPs generally have stories loosely tied to the object. Where was this corgi discovered? Who made it? Who or what made this corgi anomalous?
Concept: Seems original, though a bit bland. Is it just a corgi that kills you? If so, SCPs where the effect is 'It Just Kills You' have fallen out of favor with the community.
Other stuff:
Put your article through a grammar and spelling checker. Mistakes can distract the reader from the content of the article, no matter how good it is. For example, put spaces after periods and avoid run-on sentences.
Addendum-1a:Due to the nature of SCP-XXXX-1 skin contact with it is to be prevented at all costs. Any staff who make skin contact with SCP-XXXX are to be considered KIA and not released from the containment cell.
This should be in the special containment procedures.
