Small notification: I just edited OMG so rare archive and moved Dog Tag from June 2012 to March 2013. I was't able find any extra data about his rarity here. His rarity was last time mentioned in june 2012, when he went up in the rarity. Even old archive and one personal rarity list says, that Dog Tag went up in june 2012 and never went down again. But I just found, that it's not true.
Dog Tag went down in the rarity at january 2013 with Moonswirl. I found this proof in web time machine:
